Cardiac Blood Pool Scan is done for information on how well the heart is able to pump blood in the rest of the body. During this test, a radioactive substance called tracer is inserted into the vein. During this, a gamma camera detects radioactive substances in the lungs and heart, which has been entered into the body by injection.
Our heart pumps as much blood as possible with a beating, that percentage of blood is called injection fracture. It is guessed how well your heart is working.
