The Nuclear Perfusion Scan is used to examine the normal flow function of your blood to your heart muscles while exercising and during resting period. In the course of the procedure, a radioactive compound (called a tracer) is carefully injected into a vein in your arm. The tracer is swept from the blood rapidly through the heart muscle cells. Visual images of the heart is captured with a gamma camera. There is insufficient blood supply to certain parts of the heart when radioactivity is not detected in parts of the heart.
Why do we need Nuclear Perfusion Scan?
Your doctor might order a Nuclear Perfusion Scan if you show signs or symptoms of any chest pain with unknown causes or throughout exercises. This allows your doctor to gain information on finding out the cause of the cheat pain. Additionally, this test is useful to give a proper assessment on the blood flow to the heart walls, to ensure if there are any coronary (heart) arteries that ar blocked and the severity of the blockage.
This test is suitable following a heart attack as it allows your doctor to assess the severity of damage to your heart.
