MRI scan

An MRI (magnetic resonance imaging) scan uses a powerful magnet and radio waves to build up detailed pictures of the inside of the body. A specialised type of MRI called mpMRI (multiparametric magnetic resonance imaging) is used to help find prostate cancer. It combines the results of three MRI images to provide a more detailed image.

Your doctor may suggest you have an MRI to help work out if a biopsy is needed or to guide the biopsy needle to a specific area of the prostate. This scan can also be used to show if the cancer has spread from the prostate to nearby areas.

Before the scan, let your medical team know if you have a pacemaker or any other metallic object in your body. If you do, you may not be able to have an MRI scan as the magnet can interfere with some pacemakers. Newer pacemakers are often MRI-compatible.

Before having scans, tell the doctor if you have any allergies or have had a reaction to contrast (dye) during previous scans. You should also let them know if you have diabetes or kidney disease.


Having an MRI

Sometimes a dye (known as contrast) is injected into a vein before the scan to help make the pictures clearer. You will lie on an examination table that slides into the scanner, a large metal cylinder open at both ends. The person doing the scan will place you in a position that will allow you to stay still and limit movement during the scan.

The scanner makes loud repetitive sounds during the scan. The scan is painless but the noisy and narrow MRI machine makes some people feel anxious or claustrophobic. If you think you could become distressed, mention it beforehand to your medical team.

You may be given a mild sedative to help you relax, or you might be able to bring someone into the room with you for support. You will usually be offered earplugs or headphones to listen to music. The MRI scan may take around 30 minutes.


Medicare rebates for MRI scans to detect prostate cancer are only available if the MRI is ordered by a specialist and you meet certain conditions. You may have to also pay a gap fee. Ask your doctor or imaging centre what you will have to pay.
