| ultrasound cardiography | 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.

| ultrasound examination | <investigation> The use of high-frequency sound waves to locate a tumour inside the body. Helps determine if a breast lump is solid tissue or filled with fluids. (09 Oct 1997) |
| ultrasound guided biopsy | <procedure> The use of ultrasound to guide a biopsy needle to obtain a sample of tissue for analysis by a pathologist. (09 Oct 1997) |
| ultrasound imaging | <investigation, procedure> A technique in which high-frequency sound waves are bounced off internal organs and the echo pattern is converted into a 2 dimensional picture of the structures beneath the transducer. (12 May 1997) |
| ultrasound of the breast | <investigation> A test which uses ultrasonic waves to scan the breast. Used to evaluate fibrocystic breast disease, breast implants or breast masses. (27 Sep 1997) |
