(TRANZ-REK-tul...)
| A procedure in which a probe
that sends out high-energy sound waves is inserted into the rectum. The
sound waves are bounced off internal tissues or organs and make echoes. The
echoes form a picture of body tissue called a sonogram. Transrectal ultrasound is used to
look for abnormalities in the rectum and nearby structures, including the
prostate. Also called TRUS, endorectal ultrasound, and ERUS. |
