Cardiac Stress Test

A cardiac stress test (also referred to as a cardiac diagnostic test, cardiopulmonary exercise test, or abbreviated CPX test) is a cardio logical test that measures a heart's ability to respond to external stress in a controlled clinical environment. The stress response is induced by exercise or by drug stimulation.

This exam is used to diagnose various symptoms, including chest pain, shortness of breath, or palpitations. It helps to identify abnormal heart rhythms, to see if enough blood flows to your heart, as you get more active, see how well your heart valves are working, and to find out if it's likely that you have coronary heart disease and need more testing.


Cardiac MUGA Scan

A MUGA scan (Multiple Gated Acquisition scan) is a noninvasive test used to evaluate cardiac function. The MUGA scan produces a moving image of the beating heart, and from this image, several important features can be determined about the health of the left and right ventricles (the heart’s major pumping chambers). A MUGA scan is particularly good at giving a reading of the overall pumping ability of the heart.


Nuclear Bone Scan

A nuclear bone scan uses a radioactive tracer and high-resolution camera to identify areas of new bone growth or areas in which bone has broken down. In general, bone scans are an excellent tool for identifying and evaluating damage to bones, assessing infections and trauma, and detecting cancer that has metastasized to the bones.
