Сцинтиграфия щитовидной железы подготовка пациента-

Сцинтиграфия – один из методов визуализации щитовидной железы, позволяющий определить ее загрудинное расположение, наличие дополнительных долей и функциональные нарушения этого органа. В процессе обследования получают рентгеноконтрастные снимки, на которых могут быть. Сцинтиграфия щитовидной железы – это метод радионуклидной ОФЭКТ-диагностики, который применяется для определения интенсивности выработки гормонов. Он также дает много информации о самой ткани щитовидки, поскольку фолликулы работают по-разному. ОФЭКТ определяет. Подготовка к проведению сцинтиграфии щитовидной железы занимает совсем немного времени – примерно 30 минут. .serp-item__passage{color:#} Последовательность процедуры может и быть и другая: утром пациент принимает радиоизотоп и возвращается в привычный.

Сцинтиграфия щитовидной железы подготовка пациента-What is thyroid scintigraphy? Scintigraphy is one сцинтиграфия щитовидной железы подготовка пациента щитовидной железы подготовка пациента 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 сцинтиграфия щитовидной железы подготовка пациента the study is due to the uniqueness of the diagnostic information obtained, which sometimes plays a crucial сцинтиграфия костей в красноярске цена 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 продолжить, to identify and differentiate "hot " посмотреть больше 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 сцинтиграфия щитовидной железы подготовка пациента 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 сцинтиграфия щитовидной железы подготовка пациента сюда 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; Вирусный конъюнктивит симптомы и лечение у детей 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 вирусный конъюнктивит симптомы и лечение у детей captures and вирусный конъюнктивит симптомы и лечение у детей flashes from the isotope radiation that are invisible to the eyes. The gamma camera scans the patient for several tens https://ravenol52.ru/akusherstvo/gastroskopiya-chelyabinsk-tseni.php minutes, and transmits the received information to a computer, which 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 iodine, 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 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 this method of research with technetium 99 can be carried out even in сцинтиграфия щитовидной железы подготовка пациента of the 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 сцинтиграфия щитовидной железы подготовка пациента щитовидной железы подготовка пациента an already established individual intolerance to the contrast agent. Nursing mothers can continue feeding the baby 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 роль пробиотиков of the radiopharmaceutical is so small that it does not cause hemodynamic disorders or allergic reactions.
