(TRUS): a procedure in which a special probe is inserted rectally and uses sound waves to produce a picture of the prostate and the surrounding organs.
An image of the prostate produced when a probe is inserted into the rectum and directs sound waves to the prostate
An examination that produces an image of the prostate by inserting a probe into the rectum to direct sound waves to the prostate.
Sound waves are emitted by a probe in the rectum to produce an image, or sonogram, of the prostate.
Transrectal ultrasound uses inaudible sound waves produced by a probe inserted into the rectum to create an image of organs in the pelvis. The most common indication for transrectal ultrasound is for the evaluation of the prostate gland in men with elevated prostate specific antigen or prostatic nodules on digital rectal exam. Ultrasound may reveal prostate cancer, benign prostatic hypertrophy, or prostatitis.
