Cardiac SPECT perfusion
Cardiac SPECT Perfusion
An evaluation of the blood flow (perfusion) to the walls of your heart. Usually performed using a cardiac stress test.
What to expect
You have been scheduled for a diagnostic exam to evaluate the blood supply to your heart. You will receive up to 2 injections of a radioactive tracer that flows in the blood vessels of your heart in order to create 2 images of the blood supply to your heart, one image while resting and a second image after cardiac stress.
A small intravenous catheter will be placed in your arm. Imaging is performed twice, once at rest and a second after cardiac stress. The cardiac stress test is accomplished either by walking/jogging on a treadmill or by using a drug to challenge your heart. In total, the exam will take about 3-4 hours.
