Transrectal ultrasonography is a sensitive technique for detecting prostatic carcinoma.
Most prostatic carcinomata are hypoechoic; however most hypoechoic regions are benign.
Transrectal ultrasonography with transrectal biopsy should be performed when:
- digital rectal examination is suggestive of carcinoma
- prostate specific antigen levels are raised
Transrectal ultrasonography is also useful in the diagnosis of prostatitis.
