Echogenicity_echocardiogramAn echocardiogram (cardiac ultrasound) uses sound waves to produce images of the heart as is beating. This enables your doctor to evaluate your heart valves, the strength and thickness of your heart muscle and the size of the chambers in your heart.
Cardiac Doppler- The cardiac Doppler reveals the speed and direction of blood flow within the heart. Cardiac Doppler is helpful in evaluating valve function. The Doppler uses sound waves which reflect off the moving red blood cells within the heart chambers. It is usually performed with the 2-D Echocardiogram. Color flow mapping is usually done in conjunction with the Doppler test. IT shows speed and direction of blood flow, but the images are in color. The color allows physicians to “map” abnormalities in blood flow.
