2D And 3D Echoca

An echocardiogram is a noninvasive (the skin is not pierced) procedure used to assess the heart’s function and structures. During the procedure, a transducer (like a microphone) sends out ultrasonic sound waves at a frequency too high to be heard. When the transducer is placed on the chest at certain locations and angles, the ultrasonic sound waves move through the skin and other body tissues to the heart tissues, where the waves bounce or “echo” off of the heart structures. These sound waves are sent to a computer that can create moving images of the heart walls and valves.

Three-dimensional echocardiography (3D echocardiography) already has its established role in the evaluation of ventricular volumes and left ventricular ejection fraction (LVEF) with excellent correlation of results compared to cardiac magnetic resonance. Regarding the two-dimensional echocardiography (2D echocardiography), 3D echocardiography is closer to the real anatomy because of the absence of geometric inferences.
