Recognition of pathological changes in the human body using radioactive compounds. It is built on the registration and measurement of radiation from drugs introduced into the body. With their help, they study the work of organs and systems, metabolism, blood speed and other processes.
Two methods are used in radioisotope diagnostics: 1) A radiopharmaceutical preparation is administered to the patient, followed by examination of its movement or unequal concentration in organs and tissues. 2) Labeled substances are added to the test blood tube, evaluating their interaction. This is the like screening test for the early detection of various diseases in an unlimited number of people.
Indications for a radioisotope study are diseases of the endocrine glands, digestive organs, as well as the bone, cardiovascular, hematopoietic systems, brain and spinal cord, lungs, excretory organs, and lymphatic apparatus. It is carried out not only if there is a suspicion of some pathology or with a known disease, and to clarify the degree of damage and evaluate the effectiveness of treatment. There are no contraindications to the radioisotope study, there are only some limitations. Of great importance is the comparison of radioisotope data, x-ray and ultrasound.
Six main methods of radioisotope diagnostics are distinguished: clinical radiometry, radiography, whole body radiometry, scanning and scintigraphy, determination of the radioactivity of biological samples, radioisotope research of biological samples in vitro.
- Clinical Radiometry
- Whole body radiometry
- Determination of the radioactivity of biological samples
- In vitro radioisotope assay
