Scintioscopy

Scintiscopy is a medical imaging technique that is used to examine internal organs and tissues using radioactive isotopes. This method is based on the fact that radioactive substances introduced into the body emit gamma radiation, which is recorded by special detectors.

Scintigraphy is carried out using a special device - a scintillation gamma camera. It is a chamber that contains a radiation detector that detects gamma rays emitted by radioactive substances.

To perform scintigraphy, the patient is injected with a radioactive drug that accumulates in certain tissues or organs. The patient then passes through a gamma scintillation camera, which detects radiation from the radioactive drug.

The obtained data is processed by a computer, which creates an image of internal organs and tissues. Scintigraphy can detect various diseases, such as cancer, tuberculosis, thyroid diseases and others.

One of the advantages of scintiscopy is that it does not require invasive procedures such as biopsies or x-rays. In addition, scintigraphy can be performed several times, which allows you to monitor the dynamics of the disease.

However, like any other medical imaging method, scintiography has its limitations. For example, it does not provide information about the condition of soft tissues, and may also be associated with the risk of radiation exposure to the patient.

In general, scintigraphy is an important diagnostic method that can detect many diseases in the early stages. However, its use should be based on precise indications and doctor's recommendations.

Scintiscopies and radioscintography

\n\nScintigraphy allows you to obtain a two-dimensional image of the distribution of radionuclides in the body compared to two-dimensional radiography. In these studies, contouring of the boundaries of organs and muscles is observed, which makes it possible for a more accurate topical determination of metabolic disorders. Indications for scintigraphy are focal or diffuse changes in the structure of any organs and tissues in diffuse connective tissue diseases, various tumors and infectious processes. As an option, the technique is used when examining the whole body for cancer, pre- and postoperative examination of patients. It differs from other radioisotope examination methods in that it is as close as possible to endoscopic techniques in terms of the clarity of the resulting image. \nScintigraphic methods are based on the use of radiopharmaceuticals (RPs), which, when they enter the body, can accumulate in certain organs, be metabolized and then excreted unchanged. At the same time, a number of metabolic stages take place precisely in the target organs and structures, so that the process of accumulation and output “works” on the quality of the final image. \nWidely used to diagnose many diseases of internal organs: thyroid, kidney, liver, uterus, etc., breast tumors, gynecological diseases, as well as to monitor the effectiveness of treatment and determine tumor markers.\nThe most popular combination is radiopharmaceutical + gamma camera.
