A cardiac perfusion scan measures the amount of blood in your heart
muscle at rest and during exercise.
- Normal if radioactive tracer is evenly distributed throughout
your heart muscle.
- Abnormal if areas of abnormal tracer absorption are
present. This means some areas of heart muscle are not getting enough blood
(ischemia). This may mean that the heart has been damaged or that coronary artery
disease is present.
