Diagnostic Imaging

NUCLEAR PERFUSION STRESS TEST – EXERCISE

A nuclear exercise stress test is a diagnostic test used to evaluate blood flow to the heart. During the test, a small amount of radioactive tracer is injected into a vein. A special camera, called a gamma camera, detects the radiation released by the tracer to produce computer images of the heart. Combined with exercise, the test can help determine if there is adequate blood flow to the heart during activity versus at rest.

NUCLEAR PERFUSION STRESS TEST – PHARMACOLOGICAL

The Adenosine nuclear stress test is a diagnostic test used to evaluate blood flow to the heart. During the test, a small amount of radioactive tracer is injected into a vein. A special camera, called a gamma camera, detects the radiation released by the tracer to produce computer images of the heart. Combined with exercise, the test can help determine if there is adequate blood flow to the heart during activity versus at rest.

EXERCISE TREADMILL TEST

An exercise treadmill test is used to determine myocardial ischemia, evaluate any EKG changes during exercise, determine patient response to exercise, blood pressure response to exercise, and provide an objective basis for an exercise program.

ECHOCARDIOGRAM

An echocardiogram (often called “echo”) is a graphic outline of the heart’s movement. During an echocardiogram test, high frequency sound waves (from a hand-held wand placed on your chest) provide pictures of the heart’s valves and chambers and helps the sonographer evaluate the pumping action of the heart. Echo is combined with Doppler ultrasound and color Doppler to evaluate blood flow across the heart’s valves.

CAROTID ATERIAL DUPLEX SCAN

The carotid artery duplex scan is a sonogram or ultrasound using sound waves to visualize the arteries along the left and right sides of your neck. By checking these vessels, we can see if there is any blockage or narrowing that would inhibit adequate blood supply feeding the brain.

UPPER AND LOWER ARTERIRAL DUPLEX SCAN

A ultrasound to examine the blood flow in the major arteries and veins in the arms and legs.

UPPER AND LOWER VENOUS DOPPLER SCANS

This type of ultrasound shows if there is a blockage in a leg vein. Such blockages are usually caused by blood clots, which can be dangerous and even life threatening if they break loose and travel through the blood to the lungs. If you have pain or swelling in one leg, your doctor may order an ultrasound to determine whether your symptoms are caused by a blockage.

AORTA DUPLEX SCAN

This is a sonogram using to sound waves to visualize your aorta, the largest and main artery in the body and all of the main arteries that are attached to the aorta. Since the aorta is the main artery in the body, your physician may want you to have this test to rule out any life-threatening or limb-threatening problems which occur, but have no warning signs.
