A cardiac perfusion scan measures the amount of blood in your heart muscle at rest and during exercise. It is often done to find out what may be causing symptoms like angina (such as chest pain or pressure).
The test can show your heartâs structure (muscle, valves and chambers) and how well blood flows through your heart and major vessels. MRI of the heart lets your doctor see if your heart is damaged from a heart attack, or if there is lack of blood flow to the heart muscle because of narrowed or blocked arteries.
