Radioisotope portography

Radioisotope portography

Radioisotope portography is radioisotope angiography of the vessels of the portal vein system.

Radioisotope portography allows you to obtain an image of the vessels of the portal vein and its branches by introducing a radioactive isotope into the bloodstream and recording its distribution using a gamma camera.

When performing radioisotope portography, a solution of a radioactive substance, most often 99mTc albumin macroaggregates, is injected into the portal vein. Then, using a gamma camera, the distribution of the isotope in the vessels of the portal system is recorded.

The study provides information

Radioisotope portography (radioisotope portography) is a diagnostic method that allows you to assess the condition of the vessels of the portal vein system and its branches. This method is based on the use of radioactive substances that are introduced into the patient's blood and then removed from the body through the portal vein system into the liver.

The radioisotope portography procedure is carried out as follows:

1. The patient is injected with a radioactive substance, which is then eliminated from the body through the liver.
2. The doctor takes pictures of the liver using a special device that detects radioactive rays.
3. In the pictures you can see the distribution of the radioactive substance in the liver and assess the condition of the blood vessels.

Radioisotope portography is widely used in medicine for the diagnosis of liver diseases, such as cirrhosis, hepatitis, liver cancer and others. It can also be used to assess the condition of blood vessels during liver surgery.

However, like any other diagnostic method, portography has its limitations. For example, it cannot be used to diagnose diseases that are not related to the portal venous system, and may also cause some side effects in patients.
