An echocardiogram is a sonogram of the heart — an ultrasound exam that produces moving images of the heart's chambers, valves, and pumping function. It uses no radiation and requires no needles or recovery time.
Also called: Echocardiogram · Echo · Cardiac ultrasound · Heart sonogram
What does an echocardiogram measure?
The exam combines standard two-dimensional imaging with 3D real-time imaging, and uses Doppler ultrasound to measure the velocity of blood moving through the heart.
- Heart valve performance and valve leakage
- Abnormal communications between heart chambers
- Cardiac output and ejection fraction
- Overall heart structure and motion
What is contrast echocardiography?
For some studies, gas-filled microbubbles are injected into the venous system to improve delineation between tissue and blood. This supports evaluation of myocardial perfusion and improves flow-related measurements.
Who performs the exam?
Echocardiography at MRI Associates is performed by cardiac sonographers or physicians trained in cardiology.
How do I prepare?
No special preparation — eat, drink, and take medications as usual.
Where can I get this exam?
