Needle Biopsy of the Prostate
Needle Biopsy of the Prostate

    When doing a biopsy of the prostate, doctors usually first obtain images of the prostate by inserting an ultrasound probe (transducer) into the rectum (transrectal ultrasonography). Doctors then insert a needle through the probe and use the needle to obtain tissue samples several times (transrectal ultrasound-guided prostate biopsy).
