An MRI (magnetic resonance imaging) scan uses a powerful magnet and radio waves to build up detailed pictures of the inside of the body. Your doctor may suggest this scan to help work out if a biopsy is needed. An MRI can be used to show whether the cancer has spread from the prostate to nearby areas. It can also help guide the biopsy needle.
A specialised type of MRI called mpMRI (multi-parametric magnetic resonance imaging) is used for people suspected of having prostate cancer. This combines the results of three MRI images to provide a more detailed image.
Before an MRI scan, a dye may be injected into a vein to 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 scan is painless but can be noisy and may take 30–40 minutes. Some people feel claustrophobic in the cylinder. Talk to your doctor or nurse before the scan if you feel anxious in confined spaces. Also let them know if you have a pacemaker or any other metallic object in your body. The magnet can interfere with some pacemakers, but newer pacemakers are MRI-compatible.
|The dye used in an MRI scan or CT scan can cause allergies. If you have had a reaction to dyes during a previous scan, tell your medical team beforehand. You should also let them know if you have diabetes or kidney disease.|
|Medicare provides a rebate for MRI scans, but there may be a gap fee. There is no Medicare rebate for PET scans for prostate cancer. Ask your doctor what you may need to pay.|
