Guided Prostate Biopsy

What is an MRI Guided Prostate Biopsy?

If an earlier MRI of your prostate has shown abnormalities, your Urologist may request a second MRI 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, the MRI images are used to guide the needle into the most suspicious regions.  Some of the advantages of MRI Guided Prostate Biopsies include greater accuracy (especially with small lesions) and less trauma to the prostate with fewer needles inserted into the gland.

B. During your MRI Guided Prostate Biopsy

Procedure

We will ask you to empty both your bladder and bowel just prior to your examination. Even a small amount of gas or faecal matter within your rectum can have a significant detrimental impact to the accuracy of your results. You will also require an IV cannula in your arm. Through this we will inject a drug called Buscopan to slow down the normal peristaltic movements of your bowel and bladder for a short time. This results in much clearer images. Towards the end of the test, Gadolineum based contrast agent (dye) is injected through a vein into your arm to aid in the detection of abnormalities.

The MRI-guided biopsy can be performed with an endorectal approach or a transperineal approach. The biopsy device uses a built in endorectal coil or a guidance grid to help place the biopsy needle insertion. The biopsy needle is inserted into the prostate gland through the wall of the rectum or the perineum to remove several small samples of tissue for pathologic analysis.

Risks and side effects

An MRI Scan is a very low-risk procedure. Complications are rare during this procedure however you should be informed of the possible risks and side effects. Risks associated with this procedure include:

  • An allergic reaction to intravenous contrast material can  simulate short term allergic response such as itching, a rash or hives. A more serious allergic reaction to intravenous contrast is called an anaphylactic reaction. When this occurs, the patient may experience severe hives and/or extreme difficulty in breathing. This reaction is extremely rare, and requires emergency treatment.
  • If you have had a biopsy you may experience a small amount of bleeding from the rectum or perineum immediately after the biopsy procedure. If this occurs, it will cease with gentle pressure.
  • Blood in the sperm, urine and feces is common in the days after the procedure, but usually goes away within a week or two.
  • Infection is very rare, but can be severe if untreated. If you experience signs of infection such as fever (temperature above 38.5 degrees) and chills within a few days of the procedure, seek medical assistance immediately.
  • You may feel pain and discomfort in the area of the prostate for a day or two after the biopsy, particularly when seated.
