The scintigram is based on the administration of a minor quantity of radioactivity in the human body and provides useful information for a wide spectrum of diseases. The process is very safe, since exposure to radiation is usually smaller than that of a simple chest X-ray.

The radioactive substances enter the human body through an intravenous injection or in the form of a pill. As soon as inserted into the human body, the radioisotope is directed to the affected organ emitting Gamma rays, which are detectable by a special camera. The computer analyzes the results.

The scintigram can be applied in various ways to detect minor areas of affected tissues in cardiovascular diseases. When the radioisotopes show an increased concentration to growing tumors, the scintigram enables their detection, as well as the spread of the cancer in any part of the body.
