Description of Procedure
A perfusion heart test involves two injections of a small amount of radioactive material which looks at blood flow to the heart. An intravenous (IV) line will be placed in a vein of your arm. You will receive one injection at rest and another injection during a stress test – either exercise stress on a treadmill or drug inducted stress with Persantine medication. Two sets of pictures – one at rest and one after stress – will be taken of your heart using a special Gamma camera. You will be asked to lie on your back while the camera takes a series of pictures. When both your rest and stress pictures are complete, a Physician will interpret the images and a written report will be sent to your referring Physician. As part of our Quality Assurance Program you may be contacted in the future as a follow up to your test.
