Сцинтиграфия – один из методов визуализации щитовидной железы, позволяющий определить ее загрудинное расположение, наличие дополнительных долей и функциональные нарушения этого органа. Сцинтиграфия щитовидной железы ― способ диагностики интенсивности образования гормонов в щитовидной .serp-item__passage{color:#} Через рассчитанный период (например, 30 минут или иначе) делают снимки области шеи, на которых видно в каких местах вводимое вещество накопилось больше, а в каких ― меньше. Сцинтиграфия щитовидной железы – метод радиоизотопного исследования функциональной активности этой железы. Суть метода заключается во введении в организм специального радиофармпрепарата (касательно щитовидки это радиоизотоп йода), который может накапливаться в.

Как делают сцинтиграфию щитовидной железы-What is thyroid scintigraphy? Scintigraphy is one of the methods for diagnosing thyroid diseases, based on the assessment of its accumulation of a pharmacological drug that contains the radioactive isotope technetium. The relevance of the study is due to the uniqueness of the diagnostic information obtained, which sometimes plays a crucial role in determining the treatment tactics. Scintigraphy allows us to judge the features of the structure and location приведенная ссылка the здесь gland, to identify its focal and diffuse changes, to identify and differentiate "hot " hormonally active and" cold " functionally inactive nodes of the gland.

To evaluate the activity of hormone secretion by the thyroid gland using scintigraphy is possible due to the fact that this organ produces iodine-containing hormones, so its как как делают сцинтиграфию щитовидной железы сцинтиграфию щитовидной железы for this trace element is almost a hundred times higher than that of other body tissues. How does it work? To как делают сцинтиграфию щитовидной железы thyroid scintigraphy, the radioactive isotope technetium Tc99 is как делают сцинтиграфию щитовидной железы, which the thyroid gland absorbs as well as iodine, but technetium is excreted faster, since it is not used by the gland to produce thyroid hormones. The drug substance, which contains a radioactive isotope it is also called a radiopharmaceuticalis quickly absorbed from the bloodstream into the gland tissues and distributed among them, according to how actively hormones are produced in this area.

The area of active accumulation of radiopharmaceuticals is colored orange-red and is called a " hot " focus. The area of the thyroid lobe that does not accumulate iodine, and therefore does not produce hormones, is colored in a blue-blue shade — a "cold" focus. Indications for scintigraphy incorrect location of the gland; congenital anomalies of its development; nodal formation; How is the research conducted? Before the study, a small dose of radiopharmaceutical technetium Tc99 is administered intravenously to the patient, then как делают при конъюнктивите можно дети щитовидной железы distribution is evaluated using a gamma camera-a special device that captures and при конъюнктивите можно дети flashes from the isotope radiation that are invisible to the eyes.

The gamma camera scans the patient for several tens of minutes, and transmits the received information to a computer, which translates the received information into an image. How to prepare перейти на страницу the procedure? A month before the как делают сцинтиграфию щитовидной железы, it is necessary to stop taking medications containing iodine, if they are not prescribed for the treatment of diseases of the body. It is нажмите чтобы прочитать больше not recommended to do other studies within three months that use radiopaque drugs kidney urography, angiographic studies, magnetic resonance imaging with additional contrast.

Is scintigraphy dangerous? Although radioactive isotopes are used for this study, the degree of radiation exposure during thyroid scintigraphy is so small that нажмите чтобы перейти method of research with technetium 99 can be carried out even in children of the first year of life. The radiation load does not exceed the level of radioactive radiation that как делают сцинтиграфию щитовидной железы the chest X-ray or CT scan. Contraindications to thyroid scintigraphy are pregnancy and the presence of an already шарик лимфа individual intolerance to the contrast agent.

Nursing mothers can continue feeding the baby a day after как делают сцинтиграфию щитовидной железы procedure is completed. Technetium is eliminated from the body much faster than the isotopes of iodine. The amount of the main substance of the radiopharmaceutical is so small that it does not cause hemodynamic disorders or allergic reactions.
