Two-dimensional echocardiography is the most common cardiac ultrasound technique in use today. It provides real time, high resolution technique for a variety of cardiovascular disorders.
M-mode echocardiography provides an "ice pick" view of the heart with a very high temporal and unidismensional space resolution, so that it provides an excellent method of measure chamber dimensions and to time cardiac events.
Color Doppler echocardiography integrates the structural information provided by 2-D echocardiography with pulsed Doppler color coded flow maps that depict the direction, velocity, and turbulence of blood flow through the cardiac chambers and great vessels. Thus, a true noninvasive angiogram is now part of the cardiac ultrasound technologies.
