What is ultrasound thyroid?
Ultrasound of the thyroid gland is a diagnostic procedure performed with the help of modern ultrasound equipment.In the process of scanning, the specialist gets an opportunity to study the structure, location, size and structure of the thyroid, which is necessary to establish an accurate diagnosis and develop an optimal therapeutic course.
In addition, ultrasound can detect the presence of tumor lesions localized in the thyroid gland, assess the condition of nearby lymph nodes, the structure of the larynx and soft cervical tissue structures. To date, ultrasound is the most accurate and informative diagnostic method for thyroid pathologies.Such procedures, such as computer or magnetic resonance imaging, are already assigned for the purpose of additional research.
Note: thyroid pathologies are found, according to statistics, in 20% of patients.Therefore, in prophylactic ultrasound of this organ is recommended to do at least once a year!
Indications for thyroid ultrasound
Doctors recommend patients to perform an ultrasound examination of the thyroid in the case of the following clinical indications:
- enlargement of the gland;
- malfunction of the hormonal background;
- genetic predisposition of the patient to thyroid pathologies;
- disorders in the functioning of the endocrine system;
- problems with natural conception;
- is a disordered menstrual cycle;
- long-term therapeutic course with the use of drugs of hormonal type;
- attacks of suffocation.
- general weakness and increased nervous excitability;
Important! Patients in the age group over the age of 40 should undergo regular thyroid ultrasound for preventive purposes!
Shchitovid ultrasound is part of the compulsory comprehensive medical examination program, recommended for women during pregnancy planning .In addition, this diagnostic procedure is prescribed to patients in the period of preparation for surgical interventions to assess the condition of the gland in the postoperative period.
What are the symptoms that indicate the pathology of the thyroid?
Specialists and endocrinologists, in connection with the widespread prevalence of thyroid diseases, recommend patients to take a closer look at their health.

- sensation of a lump localized in the larynx;
- hair loss;
- increased fatigue;
- Fingertip;A slight increase in body temperature;
- sudden change in weight;
- tumor neoplasms localized in the neck or larynx;
- enlargement of the cervical lymph nodes;
- sleep disorders;
- increase in blood pressure;
- difficulty in swallowing;
- excessive sweating.
Note: , if any of the above symptoms appear, you need to contact an endocrinologist for professional advice and getting a referral for thyroid ultrasound!
Carrying out ultrasound does not adversely affect the patient's health condition, and therefore this procedure does not actually have absolute contraindications.
Doing ultrasound is not recommended for damage to the skin in the neck area in the form:
- burn lesions;
- certain diseases of a dermatological nature.

The last meal should be no later than 2 hours before the proposed study.
When going on ultrasound, bring along a clean towel( for placing under the head), napkins( to remove residual gel), as well as the results of previous diagnostic procedures of this body.In addition, in order to obtain the most accurate and reliable results of ultrasound examination on the eve of the procedure, patients should avoid excessive physical fatigue and psychoemotional shocks.

After that a special gel is applied to the skin of the patient, used to establish contact and improve the passage of ultrasound signals.
At the next stage of the procedure, the specialist presses the sensor to the patient's neck and begins to examine the thyroid gland at different angles of inclination.In the course of the study, a specific ultrasound signal is reflected from the tissue structures of the thyroid, which is processed by computer equipment, and then visualized on the monitor screen.
The specialist records the results, alternately examining the isthmus and thyroid lobes, assessing the size and structural state of the thyroid gland, after which an appropriate conclusion is made. The duration of the procedure can be from ten minutes to half an hour.
Note: The ultrasound specialist issues an opinion on the state of the thyroid gland, and the endocrinologist is already in charge of diagnosing and determining the appropriateness of additional diagnostic procedures!
What pathologies of thyroid gland does the research of reveal?

- a nodal struma;
- abnormal enlargement of the thyroid;
- cystic neoplasm;

Important !The ultrasound examination helps to identify the pathological processes localized in the thyroid gland at the earliest stages of development, which greatly facilitates the subsequent treatment and increases its effectiveness!
Norms of ultrasound of thyroid
A qualified specialist in ultrasound diagnostics is engaged in interpretation and interpretation of the results.The exact diagnosis is made to the patient by an endocrinologist.
Normally, the thyroid gland should have a standard shape and density, a homogeneous structure, smooth and well defined contours.In the absence of any disorders and pathological processes, the cervical lymph nodes are not enlarged, and cystic or tumor neoplasms are absent.
During diagnosis, great importance is attached to the size of the thyroid itself. Normally its volume in the fair sex should not be more than 18 mm, and for men not more than 25 mm.

- excluding any risks of infection of the patient during the diagnostic process;
- the possibility of conducting a diagnostic procedure without special training;
- no radiation, radiation, ionizing effects.
