Diagnostic Test
MRI Scan (mpMRI)
A detailed, non-invasive scan using magnets to create 3D pictures of the prostate. It is the primary tool used in the UK to investigate a raised PSA level and identify areas for biopsy.

Overview
About MRI Scan (mpMRI)
An MRI (Magnetic Resonance Imaging) scan uses a powerful magnetic field and radio waves to create incredibly detailed "slices" or 3D pictures of your internal organs.
In UK urology, we specifically use "multi-parametric" MRI (mpMRI). This isn't just one scan, but a series of different types of images taken during one session. These images look at the anatomy of the prostate, how blood flows through it, and how water molecules move within the tissue. This combination gives your consultant a much clearer picture of your prostate health than a standard scan.
Test Information
Understanding Your Test
A detailed guide to your diagnostic procedure — from essential preparation and the purpose of the test to safety considerations and what to expect during the process.
You will lie on a flat bed that slides into the scanner, which looks like a large, brightly lit tunnel. It is essential to stay as still as possible to ensure the pictures are sharp.
The scanner is quite loud—it makes various thumping, clicking, and humming noises while it works. You will be given earplugs or headphones (often with music) to make it more comfortable. Halfway through, you may be given an injection of a "contrast dye" (Gadolinium) into a vein in your arm; this helps specific tissues show up more clearly on the screen.
The scan itself is completely painless. The most common challenges are the loud noise and the "closed-in" feeling of the tunnel. If you suffer from claustrophobia, please tell the clinic beforehand. They can often provide a mild sedative to help you relax, or in some cases, use an "open" MRI scanner. You will have a call button in your hand to speak to the radiographer at any time during the scan.
If your PSA blood test is high or a physical examination has raised concerns, an mpMRI is usually the next step. This scan is used to see if there are any suspicious areas that might need a targeted biopsy.
It is also used to "stage" a cancer (see if it has spread outside the prostate) or to help diagnose the cause of complex pelvic pain or bladder issues.
At a glance
Preparation required
- Safety Check: You must complete a safety form. Because the magnet is so strong, it can be dangerous if you have certain metal implants like pacemakers, cochlear implants, or certain types of heart valves.
- Diet: You might be asked to avoid a heavy meal for 2 hours before the scan to reduce "bowel motion" which can blur the images.
- Clear the bowel: Some UK clinics recommend a "micro-enema" (a small, simple stool softener) before the scan. A clear rectum allows the scanner to get the best possible view of the prostate.
- Clothing: You will be asked to remove all jewellery and wear a gown or clothing without metal zips or poppers.
Risks or considerations
- Metal Implants: The strong magnets mean this scan is not suitable for everyone. Always inform your doctor of any previous surgeries involving metal.
- Contrast Reactions: Allergic reactions to the Gadolinium dye are very rare but can occur.
- Kidney Health: If you have known kidney issues, the clinical team may decide not to use the contrast dye.
- Movement: If you find it hard to lie still for 30 minutes, the images may be blurry, and the scan may need to be repeated.
What it can help diagnose
- Prostate Cancer: Specifically spotting more aggressive (high-grade) tumours.
- Benign Prostatic Hyperplasia (BPH): Non-cancerous enlargement of the gland.
- Prostatitis: Inflammation or an abscess within the prostate.
- Bladder abnormalities: Issues with the bladder wall or surrounding area.
- Pelvic Lymph Nodes: Checking if nearby nodes are enlarged or healthy.

Frequently Asked Questions
Common questions about this test and what to expect
3 questions
Radiologists use the PI-RADS (Prostate Imaging-Reporting and Data System) to score suspicious areas from 1 to 5. A score of 1 or 2 means cancer is very unlikely. A score of 3 is 'indeterminate' (middle ground), and 4 or 5 suggests a high probability of significant cancer that likely needs a biopsy.

Most modern hip replacements are MRI-compatible. However, the metal can cause 'artifact' (blurring) in the images. We use specialised software to 'metal-suppress' these images to get a clearer view of the prostate. Always inform the staff about any implants during your safety check.

No. Unlike an ultrasound, an MRI generates thousands of data points that need to be carefully processed and then 'read' by a Consultant Radiologist. Your urologist will usually book a follow-up appointment to go through the detailed report with you.
