CT-Guided Prostate Biopsy

What This Procedure Is

A prostate biopsy removes small pieces of tissue from the prostate gland so they can be examined under a microscope. In a CT-guided biopsy, computed tomography (CT) images are used to help the doctor position the biopsy needle toward the area being sampled.

Why It May Be Done

Doctors may recommend a prostate biopsy to look for cancer or other prostate conditions when other tests, such as a prostate exam or blood tests, suggest a possible problem. The tissue samples help determine whether abnormal cells are present.

How the Procedure Is Performed

The biopsy is usually done by inserting a thin needle through the area between the scrotum and anus (the perineum) or through the rectum, depending on the approach your care team chooses. CT images help guide the needle. You may receive numbing medicine and, in some cases, sedation. Several small tissue samples are typically collected.

What to Expect Afterward

You may have some soreness, light bleeding in the urine or stool, or blood in the semen for a short time after the procedure. Your care team will give you specific instructions about activity, hygiene, and warning signs to watch for. The tissue samples are sent to a laboratory, and results are usually available after a few days.
