(B) After Exercise
A nuclear stress test can help doctors find out more about the blood supply to the heart and the location of injured muscle after a heart attack.
- During this test, a radioactive substance and a special camera are used to help determine how much blood is getting to the heart muscle.
The test may be carried out before and after you exercise on a treadmill. The resting scan (“A” below) is compared to the exercise or post-stress scan ("B" below).
