It's performed similarly to a routine exercise stress test but for patients unable to exercise, pharmacologic stressors may be utilized. With nuclear stress tests, one is able to obtain perfusion images of the heart muscle and therefore get an idea if blocked heart vessels may be present (ie. obstructive coronary artery disease). CAD may prevent the heart muscle from receiving adequate blood supply during stress or periods of exercise.This frequently results in chest pain which is called angina pectoris. Perfusion imaging usually consists of stress and rest tests. Images are taken of your heart while at rest and after exercising or under stress. This allows your physician to compare blood flow during stress and rest.
Decision whether or not more invasive cardiac procedures are needed can then be made. We ensure highest quality nuclear imaging and protocols with our nuclear laboratory accredited by ICANL.
