Your doctor may order additional testing if this test is abnormal. This test always includes an ABI (ankle-brachial index). Blood pressures are taken in both arms and ankles. The pressures are compared and calculations performed to estimate the severity of the disease.

The test will help your doctor determine if there are areas of your heart that do not receive enough blood supply due to coronary artery disease. Areas of your heart that may have been damaged from a previous heart attack may also be seen.

You will be given an injection of the radioactive imaging agent during the infusion. Following the Adenosine infusion, pictures will be taken to determine blood flow to the heart muscle.
