What is Thallia scanning?
Thalia scan involves injection of a very small amount of radioactive thallium into the vein of the patient undergoing test. The amount used is so small that it does not produce a harmful amount of radiation for the patient. Although radiation is not harmful to adults, a pregnant woman must inform her doctor before the test to ensure the safety of the fetus. As the test goes, monitors are used to monitor radioactive thallium as it passes through the bloodstream.
During the scanning of Thalia, a small amount of radioactive substance is used to create images of a particular body. This test is usually used to explore the heart or brain and determine whether these areas receive enough blood. Thallia scanning is often combined with an exercise test to determine how well the heart works in stress.
Thallia scanning is often combined with an exercise test. In this type of test, the initial injection of Thallia is managed, while the patient walks on the treadmill. Another injection is given at other times, toWhen the heart is calm. By comparing two sets of results, the doctor can determine whether any areas of the heart receive insufficient blood supply either at rest or after exercise.
At the beginning of the test, the patient begins for several minutes by exercising on the treadmill. Its heart rate and blood pressure are monitored at all times. About a minute before he stops exercising, Thallium is injected into a vein. During the remaining minute of the test part of the test, radioactive thallium is undergoing a bloodstream and reaches the heart. As soon as they enter the heart, Thallium accumulates in places that have sufficient blood supply.
At the end of the exercise period, the patient is immediately scanned using a display camera, so the location of the radioactive thallium can be determined. The hearts that have accumulated thallium are considered to be a good approach to blood supply. Any area of heart that has a smaller Thalium or none at all has a limited supply of blood.
Thalia scan determines the heart areas that do not have sufficient supply of blood and oxygen. In people who had a heart attack, it is common for certain areas of heart to suffer damage that reduces blood flow both in peace and during exercise. People who are threatened by a heart attack often show signs of reduced thallia accumulation after exercise. Therefore, the test helps doctors to determine people who are at risk of heart attack and other heart problems.
