| echocardiography | Echocardiography is a diagnostic test which uses ultrasound waves to make images of the heart chambers, valves and surrounding structures. It can measure cardiac output and is a sensitive test for inflammation around the heart (pericarditis). It can also be used to detect abnormal anatomy or infections of the heart valves.

| echocardiography, doppler | Measurement of intracardiac blood flow using an m-mode and/or two-dimensional (2-d) echocardiogram while simultaneously recording the spectrum of the audible doppler signal (e.g., velocity, direction, amplitude, intensity, timing) reflected from the moving column of red blood cells. (12 Dec 1998) |
| echocardiography, doppler, colour | Echocardiography applying the doppler effect, with the superposition of flow information as colours on a gray scale in a real-time image. (12 Dec 1998) |
| echocardiography, doppler, pulsed | Echocardiography applying the doppler effect, with velocity detection combined with range discrimination. Short bursts of ultrasound are transmitted at regular intervals and the echoes are demodulated as they return. (12 Dec 1998) |
| echocardiography, four-dimensional | Dynamic three-dimensional echocardiography using the added dimension of time to impart the cinematic perception of motion. (mayo clin proc 1993;68:221-40) (12 Dec 1998) |
| echocardiography, three-dimensional | Echocardiography amplified by the addition of depth to the conventional two-dimensional echocardiography visualizing only the length and width of the heart. Three-dimensional ultrasound imaging was first described in 1961 but its application to echocardiography did not take place until 1974. (mayo clin proc 1993;68:221-40) (12 Dec 1998) |
| echocardiography, transesophageal | Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues using a transducer placed in the oesophagus. (12 Dec 1998) |
| ultrasonography, doppler, duplex | Ultrasonography applying the doppler effect combined with real-time imaging. The real-time image is created by rapid movement of the ultrasound beam. A powerful advantage of this technique is the ability to estimate the velocity of flow from the doppler shift frequency. (12 Dec 1998) |
| uterus duplex | Any uterus with double lumen (u. Didelphys, uterus bicornis bicollis, or septate uterus). Synonym: uterus duplex. (05 Mar 2000) |
