On ultrasound, prostate cancer is characterized by hypoechoic areas.

Transrectal ultrasonography (TRUS) is often initially performed in order to detect abnormalities and to guide biopsy, usually following an abnormal PSA level or DRE result.^[2]
Ultrasound is used to direct biopsy of suspicious, hypoechoic regions, usually in the peripheral zone.
Transrectal ultrasound is also the modality of choice for directing brachytherapy seeds into the prostate gland.
