What is an MRI Guided Prostate Biopsy?

Octreotate PET-CT Scan

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.

What to bring

  • Your request form

You will be asked to fill out a MRI Safety Check list to confirm you do not have any contraindicated items or implants in/on your body. The MRI Technologist will ensure that no potentially unsafe items enter the scan room.

B. During your MRI Guided Prostate Biopsy


The MRI-guided biopsy can be performed with an endorectal 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.

What happens after an MRI Guided Prostate Biopsy?

How do I get my results?

Immediately after the Octreotate PET-CT scan you may be asked to wait until your images are checked for diagnostic quality.

If you have moved during the scan you may be asked to stay until an additional image of the affected body part can be taken. If the scanned is deemed to be of good quality you may then leave the department and resume your daily activities. There are no residual effects from the tracer or the scan.

Your images will be reviewed along with your relevant medical history, and any other imaging, and be reported on by our Nuclear Medicine Radiologist or Nuclear Medicine Physician.

If your results are needed urgently, or you have an appointment straight after your scan with you referring doctor or health care provider, Envision Medical Imaging will arrange to have your results available immediately. Otherwise your referring doctor will receive your report within 48 hours of your examination. Please ensure that you make a follow up appointment with your referring doctor to discuss the results.

Post procedural information

After your scan you will be able to return to your normal daily activities.
