Imaging
Echocardiography
Echocardiogram
Ultrasound of the heart performed by moving a probe across the surface of the chest with the aid of a gel
Evaluates the heart walls and valves
Gives an estimate of the pumping strength of the heart
No prep necessary
Stress Echocardiogram
Echo images of the heart before and after a stress test, looking for differences between the two sets of pictures
The stress portion may be performed with a treadmill or bicycle
Please wear comfortable clothing and tennis shoes
No prep necessary
Vascular
Ultrasound performed by moving a probe across the surface of the body with the aid of a gel
Types of Vascular Imaging:
Abdominal Aorta – evaluates blood flow of the large artery that runs through the abdomen and rules out an aneurysm
Carotid Doppler – evaluates blood flow of the arteries in the neck
Upper Arterial (BRI) – evaluates blood flow of the arteries in the arms
Lower Arterial (ABI) – evaluates blood flow of the arteries in the legs
Venous Doppler – evaluates blood flow of the veins in the legs and rules out blood clots
Renal Ultrasound – pictures of the kidneys and blood flow to the kidneys
Allen’s test – evaluates the radial artery in the wrist for radial Catheterization
Special prep:
For Abdominal Aorta ONLY – patient must be without food for at least 4 hours
For Renal Ultrasound ONLY – patients should drink numerous glasses of water before the test so that they will be well-hydrated, making images better
Nuclear
Cardiolite Stress Test
Evaluation for heart vessel blockage
Two sets of images with a stress test in between
Stress test portion may be performed on a treadmill or with patient given an IV stress chemical
May be ordered as a one-day or two-day test
Special prep:
⁃ NO CAFFEINE for 12 hours before test, including decaf drinks and chocolate
⁃ Other instructions will be given when the test is scheduledMUGA Scan
The most accurate way to measure the heart’s pumping function
Blood is drawn, tagged to a tracer, then given back to patient
Two sets of images are performed
No prep necessary
