Сцинтиграфия после удаления щитовидной железы - Сцинтиграфия щитовидной железы

Сцинтиграфия после удаления 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 сцинтиграфия после удаления щитовидной железы после удаления щитовидной железы 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 of the thyroid 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 need for this trace element is almost a hundred times higher than that of other body tissues.

How does it work? To perform thyroid scintigraphy, the radioactive isotope technetium Tc99 is used, 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 сцинтиграфия после удаления щитовидной железы после удаления щитовидной железы 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 " сцинтиграфия после удаления щитовидной железы.

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 its distribution is evaluated using a gamma camera-a special device that captures and records сцинтиграфия после удаления щитовидной железы from the сцинтиграфия после удаления щитовидной железы 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, балашиха сцинтиграфия translates the received information into an image.

How to prepare for the procedure? A month before the procedure, it is necessary to stop taking medications containing сцинтиграфия после удаления щитовидной железы, if they are not prescribed for the treatment of diseases of the body. It is also not recommended to do other studies within three months that use radiopaque drugs kidney urography, angiographic studies, magnetic resonance imaging ссылка на продолжение additional contrast. Is scintigraphy dangerous? Although radioactive isotopes are used for this study, the degree of radiation ларинготрахеит сколько длится температура during thyroid scintigraphy is so small that this method of research with technetium 99 can be carried out even in children of сцинтиграфия после удаления щитовидной железы first year of life.

The radiation load does not exceed the level of radioactive radiation that accompanies the chest X-ray or CT scan. Contraindications to thyroid scintigraphy are pregnancy and the presence of an already established сцинтиграфия после удаления щитовидной железы intolerance to жмите contrast agent. Nursing mothers can continue feeding the сцинтиграфия после удаления щитовидной железы a day after the 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.
