MODEL RELEASED. Prostate biopsy using transrectal ultrasound. A biopsy is used to diagnose cancer or other disorders. An ultrasound scanner uses sound waves to build internal images of the body. During a transrectal ultrasound a transducer(in right hand) is inserted into the rectum via the anus. The transducer emits high- frequency sound waves and detects the reflected echoes. The results are used to build the image,which is displayed on the monitor (upper left). The image is used to guide a needle (in left hand) that removes some prostate cells for examination. The prostate is a small gland found just below the bladder surrounding the urethra,the tube urine passes through. Prostate cancer is most prevalent in men over 50 years of age | |
