Nuclear Stress Test

This test measures blood flow to your heart at rest and while your heart works either through exercise or medication. This test provides images of your heart that show areas of poor blood flow from blocked coronary arteries (CAD/coronary arterial disease) and areas of tissue damage to the heart.

A radioactive dye will be injected into your bloodstream. Two sets of images will be taken – one prior to the exercise/pharmaceutical portion and one afterwards.

This test is performed to determine if you have coronary artery disease (CAD) and to see the shape and size of your heart.
