We will obtain a brief history emphasizing current symptoms and pertinent family history. An IV line is inserted into your arm and electrodes are attached to your chest. The first dose of imaging agent is injected through the IV. Resting images are obtained at least 60 minutes later while you lie on a table with the nuclear camera moving around your chest.  A stress test is performed on a treadmill with an EKG monitored by a physician. A second set of images is obtained at least 20 minutes after the treadmill test. 
The test takes approximately four to six hours.
