CT-Guided Prostate Biopsy

What is a CT-Guided Prostate Biopsy?

If an earlier scan of your prostate has shown abnormalities, your Urologist may request a biopsy in order to find out exactly what is the matter. During this scan any visible abnormalities will be biopsied with a needle. During the scan, Computed Tomography images are used to guide the needle into the most suspicious regions.

B. During your a CT-Guided Prostate Biopsy

Procedure

When you are transferred to the CT room you will be made comfortable on the examination table. The examination table slides you into the centre of the CT machine and some preliminary pictures are taken to confirm the scan position and the area of needle entry marked on your skin.

Your skin will then be cleaned and a local anaesthetic will be injected into site. This may temporary sting until the skin becomes numb (up to 30 seconds).

The doctor will use CT guidance to determine the location of your prostate. He/she will then insert a thin tube, called the needle guide. The doctor will connect the needle guide to a biopsy apparatus.

It may be necessary to make more than one pass of the needle to achieve the proper location and ensure an adequate sample is taken for testing.
