Ultrasound examination of the thyroid gland is a high-frequency method that guarantees with a high degree of accuracy the detection of the smallest tumors, nodes and cysts at the earliest stages.
A characteristic feature is the fact that preparation for an ultrasound of the thyroid gland is not needed, since it is not expected to have an intense effect on the internal organs.
The implementation of this simple recommendation will save the patient from discomfort during the procedure when the device is pressed on the organ. Traditionally, ultrasound examinations are demanding and require special training. To understand this issue, you can familiarize yourself in detail with all the nuances of ultrasound of the thyroid gland.
Survey technique
The study is carried out according to the standard scheme, it is proposed to lie on your back, placing a roller under the cervical vertebrae. The doctor will need to lubricate the area of the neck and the thyroid gland itself, for which he uses a special gel. It is assumed that the doctor will install the sensor at different angles relative to the organ, which will provide the most informative images.
Attention! The patient will not be deeply influenced by ultrasound, it is assumed that there is little contact through the skin with the examined organ. The ultrasound beam easily penetrates the tissues, which does not cause discomfort to the patient.
It is for this reason that preparation is simply not needed, but this does not relieve the patient of the need to take a responsible approach to the procedure.
Parameters and normal state of the organ
After performing an ultrasound examination of the thyroid gland, the doctor must provide printed results containing information about the condition of the organ. The specialist determines only two parameters by which he can accurately identify possible pathologies. We are talking about the volume of the organ, which normally does not exceed 25 mm for men, and for women this figure is 18 mm, provided that the contours are clear. Thyroid tissue is one of the main elements of the structure of the organ, the doctor must identify the level of echogenicity to find out how homogeneous it is.
Important! If an ultrasound of the thyroid gland reveals heterogeneity, then this may be a sign of inflammation and the presence of a tumor.
In addition, during the ultrasound examination, it is assumed that the lymph nodes are palpated, if there is tissue heterogeneity in combination with their increase, then this is a sure sign of oncology.
Indications for the study
The examination is absolutely harmless, no preparation is required, more than that, it is allowed to perform it an unlimited number of times, since the body is not irradiated. However, there is one more unresolved issue that may well reveal the need for some preparatory measures. It is necessary to consider the indications for an ultrasound of the thyroid gland. Perhaps certain categories of people, to the extent of certain disorders, still need preparation for the examination ...
Initially, it is necessary to single out a group of high-risk citizens, that is, having some swelling in the indicated area, perhaps the lymph nodes are strongly hypertrophied or a goiter has appeared. You may also need an ultrasound of the thyroid gland in case of hormonal imbalance, which was detected during a blood test. We can safely say that preparation in these cases is not required, since we are not talking about a deep impact on the organ, because the cause can be identified in the standard mode.
Women need an ultrasound scan of the thyroid gland in the following cases:
- Imbalance in the menstrual cycle
- Age limit over 35 years old
- Pregnancy
- Diagnosing infertility.
Here we are also talking about a standard procedure, in which preparation is simply not needed.
It can be concluded that examination of the thyroid glands using ultrasound is a safe and effective method. It is characteristic that the field of it eliminates the need for other methods of organ examination: MRI; CT. Using ultrasound, you can be sure of the reliability of the picture obtained, since it is possible to identify all known abnormalities, congenital pathologies. Just visit your doctor and get the result within minutes.
Ultrasound of the thyroid gland is a diagnostic study designed to detect organ pathology without surgery. The procedure is prescribed to the patient with minimal suspicion of endocrine system pathology.
Based on the results of ultrasound diagnostics, the doctor assesses the condition of the thyroid gland and nearby organs (larynx, lymph nodes, parathyroid gland). The data obtained as a result of examination of the thyroid gland helps to establish the correct diagnosis and prescribe treatment.
Why is an ultrasound examination of the thyroid gland prescribed?
The thyroid gland is a hormone-producing organ that affects the functioning of all systems of the human body. The thyroid hormones produced by it affect the processes of thermoregulation, metabolism, the work of the brain, the cardiovascular and genitourinary systems. Ultrasound of the thyroid gland is performed in order to timely diagnose pathologies of the endocrine system.
It is recommended to carry out a preventive examination at least once a year. Thyroid examinations for women over 35 who are at increased risk for thyroid disease should be regular. A timely ultrasound examination of the thyroid gland will help diagnose pathological conditions of the organ in the early stages, which will allow for effective therapy.
The indications for the procedure are the following situations:
- planning pregnancy;
- period of bearing the child;
- violation of the menstrual cycle;
- sore throat not associated with colds (perspiration,);
- an increase in the thyroid gland;
- the presence of seals in the neck area;
- a patient's history of a hereditary predisposition to the onset of diabetes mellitus and other endocrine diseases;
- deviation from the norm in the tests for thyroid hormones;
- iodine deficiency due to living in unfavorable ecological regions;
- work in hazardous industries;
- long-term use of hormonal drugs;
- increased fatigue;
- lethargy and apathy;
- nervousness, anxiety and irritability;
- unreasonable weight gain or weight loss;
- hand tremor;
- hair loss;
- suspicion of tumor formations.
Is preparation required for the procedure?
Before doing an ultrasound of the thyroid gland, you need to prepare for the procedure. First of all, the patient should consult a doctor who will explain the rules for conducting the study. Preparing for an ultrasound of the thyroid gland does not present any difficulties for the patient, since the gland is a separate organ that is not associated with the digestive system. Therefore, there are no restrictions related to the consumption of certain foods.
The only condition that applies to elderly people and children is to skip one meal just before the examination. The implementation of these recommendations will help prevent the occurrence of a gag reflex, while pressing the sensor on the organ.
If necessary, the patient, before undergoing ultrasound diagnostics, the doctor may prescribe a blood test for hormones of the endocrine system. During which the level of such indicators will be determined:
- T3 free;
- T4 free;
- Thyroid stimulating hormone (TSH);
- Thyroglobulin (TG);
- Antibodies to TG;
- Antibodies to TPO.
It is necessary to take with you the results of previous ultrasound examinations, if any. You may also need a disposable diaper and a towel to remove the remaining gel from the neck.
How is the examination carried out?
How is an ultrasound of the thyroid gland done? A special sensor is placed on the thyroid gland, which sends an ultrasound signal. The gland reflects it, after which the resulting black and white image of the organ is displayed on the screen of the ultrasound apparatus. In places of pathological changes, the intensity of the color will change.
Despite the fact that the thyroid gland is an internal organ, it is located very conveniently and this allows the procedure to be carried out absolutely painlessly. The only unpleasant moment is discomfort in the neck associated with an uncomfortable head position.
Stages of the procedure:
- the patient lies down on the couch and throws his head back;
- the doctor applies a special gel to the neck, which promotes better transmission of ultrasonic waves;
- with the help of a special sensor that generates ultrasound waves, an examination is carried out at different angles.
It is not necessary to have a doctor's prescription for the procedure. You can independently contact the diagnostic center, sign up for a consultation with an endocrinologist and find out how much an ultrasound of the thyroid gland costs.
Deciphering the examination results
Ultrasound examination helps to assess the following indicators of the thyroid gland:
- organ location (typical or atypical);
- structure (number of lobules);
- size (normal, enlarged or reduced);
- organ contours (clear or blurred);
- the structure is homogeneous or heterogeneous);
- tumor formations.
What does an ultrasound of the thyroid gland show? During the diagnosis, you can see not a specific disease, but only indirect signs that may indicate a variety of diseases. After the examination, it is necessary to visit an endocrinologist, who will decipher the ultrasound of the thyroid gland. During the study, both specific symptoms (indicating the presence of a specific disease) and nonspecific (which are signs of many diseases) can be identified. In some cases, ultrasound of the parathyroid glands and nearby lymph nodes can be additionally performed.
Deciphering the results of ultrasound of the thyroid gland is generalized information that takes into account a large number of indicators that play an important role in the correct diagnosis of the disease.
An important diagnostic indicator is the structure of the thyroid gland, which should be homogeneous, consisting of small follicles that produce hormones. Which, in turn, play an important role in the functioning of many systems of the human body, regulating metabolism. Normally, there should be about 30 million follicles.
When determining the size of the gland, only the lobes are taken into account. The isthmus does not significantly affect the diagnosis of organ diseases. Both its presence and absence are considered the norm.
conclusions
If a hypoechoic thyroid nodule is identified, then you should consult an endocrinologist for a consultation. The doctor will study its structure, determine whether there is no or presence of blood flow in them. An important indicator will be the contours of the identified formation. The final results of an ultrasound examination can alert the patient, as they may be signs of cancer. Therefore, you should remember the main rule: ultrasound indicators are just criteria for assessing the functional state of the endocrine system. But, by no means is it a diagnosis of the disease.
Ultrasound examination of the thyroid gland has become possible relatively recently. Prior to this, the diagnosis was made on the basis of external examination and palpation. Thanks to ultrasound of the thyroid gland, today it is possible to detect organ pathology even at the initial stage of development. This procedure is completely safe and painless. And yet, patients are interested in how an ultrasound of the thyroid gland is done, what is the preparation for the procedure.
Thanks to an ultrasound study, today doctors can timely determine the presence of pathologies:
- Changes in the size of the thyroid gland, the formation of a toxic goiter;
- The formation of various tumors;
- Corrections in the structure of the gland, indicating inflammation or the appearance of a cyst;
- Formation of fibrous tissue in the lobes of the thyroid gland;
- Metastases with suspected malignant neoplasms.
When ultrasound scanning is required
Ultrasound of the thyroid gland makes it possible to timely detect and begin to treat such severe ailments as adenoma, hypothyroidism, cyst, goiter and oncology.
Symptoms that signal the need for immediate medical attention are:
- unexplained sudden weight loss or, conversely, obesity;
- chills, feeling of constant cold or, conversely, increased sweating;
- unmotivated breakdown;
- indifference to external factors, depression;
- feeling of constant sleepiness;
- unreasonable mood swings (not only during menstruation);
- unexplained rise in temperature (37-38 o C);
- swelling in the neck;
- feeling of a "lump" in the throat;
- tachycardia;
- peeling of the skin, fragility of the nail plates, hair loss;
- tremor;
- sleep disturbance;
- swelling of the limbs;
- increased irritability.
In addition to the listed symptoms, an ultrasound of the thyroid gland without preparation for the procedure is prescribed in the following cases:
- the growth of a goiter or lymph nodes,
- disrupted menstrual cycle, planning pregnancy, causeless infertility,
- deviations of hormone levels in the blood from the norm,
- control over the work of the thyroid gland after surgery,
- frequent change of climatic zones,
- age is more than 40 years for men, for women - over 35,
- constant intake of hormonal medications,
- prolonged exposure to ultraviolet radiation,
- a genetic tendency to pathologies of this organ.
The thyroid gland is a special “microcomputer” of our body, which is engaged in the production and regulation of thyroid hormones and controls the life of our body.
One has only to "get out of hand" this small detail, and our body begins to suffer, ache and collapse.
Therefore, it is very important to timely examine the thyroid gland for the presence of pathologies. An ultrasound of the thyroid gland will help identify some of them. No special training is required to conduct this study.
Ultrasound of the thyroid gland is an easy, fast, affordable way for everyone to diagnose various pathologies, such as the formation of cysts and nodes, or an increase in the size and volume of the gland, and it will also allow us to assess the structure of its tissues.
Investigations are carried out using directed ultrasonic waves, which make it possible to "enlighten" the organ and assess the degree of changes in its tissues, blood vessels, and reveal some disturbances in the functioning of the gland.
Ultrasound examination of the thyroid gland is carried out in a specially equipped medical office. The specialist puts the patient on a couch, while the subject's head is tilted back a little to provide easy access to the neck surface.
The doctor then applies a little whitish-transparent gel to the patient's skin, which is a "conductor" for the ultrasound beams. Further, the study is carried out using a special ultrasound sensor, which the specialist presses to the patient's skin, in the area of the thyroid gland.
Ultrasound beams, reflected from the gland, return to the sensor and are further processed by a computer, and a picture showing the thyroid gland is displayed on the monitor. Each parameter is recorded in the medical record: volume, size of lobes, isthmus. If the patient has nodes or cysts, then the doctor describes them in detail. Then the specialist compares the obtained data with normal parameters.
Thyroid ultrasound scan
The thyroid gland ultrasound procedure is over: now the patient, having received the results, is sent to an endocrinologist, who will establish a diagnosis or send for additional examinations, and then prescribe treatment.
An ultrasound scan is often not enough to make the correct diagnosis, so tune in to the fact that the endocrinologist will write you directions for other studies or analyzes.
When is it better to carry out an ultrasound
In order not to miss the moment when the thyroid gland begins to malfunction, its ultrasound examination should be carried out as a preventive measure once every six months. It is especially important for women to undergo an ultrasound scan, because the thyroid gland is the "second heart" of the fairer sex. Thanks to a timely study of pathology, it can be detected at early stages, which will greatly simplify further treatment.
An ultrasound of the thyroid gland must be done without delay for those who experience the following symptoms:
- feeling of a lump in the throat;
- fluctuations in weight;
- tremor of the limbs;
- nervousness;
- body temperature, which lasts for a long time in the range of 37-38 degrees;
- drowsiness;
- hair loss, brittle nails;
- irregular heart rate.
It is important to undergo an ultrasound scan of the thyroid gland for women who want to become a mother for a long time, but cannot get pregnant or observe menstrual irregularities in themselves, people from the age of 40, those who take hormonal drugs. Patients with diabetes mellitus and people whose professions are associated with occupational hazards are also under the supervision of an endocrinologist.
By the way, ultrasound of the thyroid gland is also used during biopsy - puncture of the thyroid gland, when samples of its tissues are taken for analysis to determine their structure. This is important for nodes, when the doctor needs to make sure that the nodes do not develop into cancerous tumors.
You should not self-medicate and diagnose yourself with a thyroid gland. With the main hormonal computer of the body, jokes are bad.
Thyroid ultrasound - how to prepare?
Thyroid ultrasound is a simple and quick diagnostic method that does not require any special preparations.
You can choose absolutely any day for conducting the research.
You can also choose any time of the day to have an ultrasound of the thyroid gland.
Preparing for an ultrasound of the thyroid gland is simple.
Before visiting the ultrasound office, do not limit yourself in movement or food, lead your usual lifestyle. At the appointment, you can take a clean towel with you to wipe off the gel, and a sheet to lay on the couch (this is important for small towns, where clinics often save on disposable sheets and napkins).
It is best to come to ultrasound of the thyroid gland 7-9 days after the end of menstruation, experts say.
Treatment of nodular goiter should be carried out under the supervision of a physician, but alternative methods of treatment can also be used as additional therapy. , proven recipes.

The health of the thyroid gland significantly affects the functioning of the entire body. It releases hormones important for metabolic processes in the body. Disruptions in the work of this important body system provoke a deterioration in the general state of health. Consider preparing for an ultrasound examination of the thyroid gland.
Some diseases of the thyroid gland are life-threatening, therefore, ultrasound of this part of the endocrine system of the body is considered a very important diagnostic procedure, which is regularly recommended for every modern person.
It is now quite simple to make an ultrasound of the thyroid endocrine gland, since the required equipment is available in almost every modern hospital. Some clinics conduct examinations free of charge, sometimes you need to pay for diagnostics, but the cost will always be available for each patient.
How is an ultrasound of the thyroid gland
The procedure is quite simple and painless. Before the examination, the patient lies down on a bed, next to which there is a diagnostic device. Before starting, the doctor applies a special gel to the patient's neck, which has no color or smell. This substance significantly enhances the penetrating ability of ultrasonic waves. In the process, the doctor drives a special ultrasound sensor in the area of the patient's neck in the areas under study, while simultaneously reading information from a special monitor. The analysis of the results takes quite a bit of time, so the conclusion can be obtained only 20-30 minutes after the end of the examination.
The principle of carrying out is based on the properties of a sound wave at ultrahigh frequencies to fight off any objects. A special sensor emits waves, the field of which captures their reflection. The equipment processes the received signal, after which it displays an image of the structure of the examined tissues. The clarity of the image is obtained sufficient to identify abnormalities in the work of the endocrine system, as well as to determine the key characteristics of the gland itself.
A person who is far from medicine will not be able to make out the image on the screen of the diagnostic apparatus, however, experienced specialists will be able to obtain a lot of information using the data that can be obtained by exposure to ultrasound waves.
Is ultrasound mandatory
Regular checking of the state of the elements of the endocrine system of the body is not mandatory. The patient will not be forced to undergo this procedure, nor will they be able to refuse to provide other medical services. Unlike diseases that are detected by such a mandatory diagnostic study as fluorography of the lungs, ailments of the organs of internal secretion do not pose a threat to the public, because of this, each patient is responsible for his own state of health, and also independently determines the schedule of medical examinations. However, experts emphasize that it is better to examine the state of the thyroid gland at least once every six months.
Is ultrasound safe for health
Ultrasound has minimal effect on internal organs. The load on the body with this procedure is much lower than with x-rays. However, the high-frequency sound is still minimal, but it affects the health of the body. There will be no damage from a one-time procedure, but you should not abuse it too much.
It is quite safe to visit an endocrinologist for ultrasound diagnostics once every six months, and in case of problems, you can increase the number, the procedure will not cause much damage to the body.
Where is the best place to undergo the ultrasound procedure
Medical institutions in Russia are not funded equally everywhere. While some medical facilities still use old equipment to serve patients, others use advanced medical technology.
The accuracy of the results and the safety of the procedure significantly depend on the condition of the equipment.
Ultrasound in general is considered safe for the body in small quantities, however, modern technologies make it possible to achieve higher image quality with a lower intensity of exposure. If there are no modern state clinics in the village, then it would be advisable to contact a private institution, since the cost in any case will be low.
What allows you to determine the ultrasound of the thyroid gland
The human neck has a very complex structure. There are many important blood vessels, lymph nodes, and the thyroid gland, which is responsible for many metabolic processes. Ultrasound examination allows you to determine the state of an important element of the endocrine system. It will help to determine the volume of the thyroid gland, which in men should not exceed 25 cubic centimeters, and in women - 18. It will also help to determine the homogeneity of tissues, the contours of the organ, density, the presence of foreign formations (tumors, cysts), check the state of important lymph nodes and blood vessels ...
The examination will help to detect problems in the functioning of the endocrine system of the body, which are caused by diseases of the thyroid gland. Any malignant and benign formations in this area pose a significant threat to life and health. A regular check of the thyroid gland will help to timely detect the development of a cyst or cancer. In a situation with cancer, timely diagnosis gives additional chances to save life.
When is an ultrasound of the thyroid gland prescribed?
This study is prescribed when visiting an endocrinologist. The need to go for an ultrasound examination is usually indicated by:
- weakness;
- rapid loss of performance;
- lack of mood and appetite;
- discomfort in the throat;
- a feeling of a foreign body in the throat;
- intense hair loss;
- fever and sweating;
- sensation of foreign bodies, which are palpable;
- suspicions of developing cancer.
All the symptoms listed above indicate metabolic disorders in the body, which may be caused by malfunctions of the thyroid gland. Also, some symptoms indicate life-threatening conditions. The development of tumors in the throat is a direct lethal threat, so it is very important to detect them as soon as possible.
Preparation for the ultrasound procedure
Many patients do not know how to prepare for an ultrasound examination of the thyroid gland. Special preparation for an ultrasound scan is not required, which makes the study quite convenient for people who are busy at work most of the time.
Preparation for an ultrasound scan is that you need to take a towel with you, since it must be laid on the bed where the diagnosis will be carried out. Also, a towel is needed to remove the remaining gel from the neck. It is worth remembering that during the process, the doctor may put a little pressure on the throat, which sometimes provokes a gag reflex. Young people who do not suffer from digestive problems, as a rule, withstand the procedure without the manifestation of a gag reflex. However, older patients are advised to undergo the procedure on an empty stomach. Since most ultrasound examinations are performed in the morning, it may be advisable to prepare for an ultrasound in the form of refusing to eat before undergoing the examination to avoid discomfort.
