This progressive department evaluates coronary artery disease by assessing blood flow to the heart and identifying blocked arteries. Staffed by nuclear medicine technologists and EKG technicians, the department performs procedures like myocardial perfusion imaging.
What to Expect
A myocardial perfusion imaging test takes 2-3 hours. A technologist explains the process, which involves injecting a radiopharmaceutical intravenously. Heart images are taken 30-45 minutes later, with the patient lying on a scanning table for about 20 minutes. Initial images show blood flow at rest.
Electrodes are then attached to monitor the heart during exercise or stress, overseen by a cardiologist. Exercise can be done on a treadmill or with drugs like adenosine or dobutamine. After 30-45 minutes, a second set of images is taken to assess post-exercise blood flow. A nuclear cardiology technologist processes the data, and a cardiologist interprets the results.
Preparation
No fasting is needed, but avoid caffeine, including decaf, for 12 hours before the test. Wear comfortable, metal-free clothing.
