Prostate MRI Scan: Complete Guide

A prostate MRI scan is the most detailed imaging method for evaluating the prostate gland, offering superior soft tissue resolution compared to ultrasound or CT. Prostate MRI plays a critical role in detecting, characterising, and staging prostate cancer, as well as assessing benign prostate conditions. Lola Health offers private prostate MRI scans at over 150 UK centres.

What a Prostate MRI Scan Shows

• Prostate cancer — multiparametric MRI (mpMRI) can detect clinically major prostate cancer with high accuracy, using a standardised scoring system (PI-RADS).
• Benign prostatic hyperplasia (BPH) — enlargement of the prostate gland causing urinary symptoms.
• Prostatitis — inflammation or infection of the prostate.
• Cancer staging — assessing whether cancer has spread beyond the prostate capsule, to the seminal vesicles, or to nearby lymph nodes.
• Post-treatment surveillance — monitoring for cancer recurrence after surgery or radiotherapy.
• Anatomical assessment — evaluating prostate size, shape, and relationship to surrounding structures.

When You Might Need a Prostate MRI Scan

• Elevated PSA (prostate-specific antigen) blood test results
• Abnormal digital rectal examination (DRE) findings
• Before a prostate biopsy — MRI can guide targeted biopsies to suspicious areas
• Persistent urinary symptoms (frequency, urgency, poor flow, nocturia)
• Family history of prostate cancer
• Staging of diagnosed prostate cancer before treatment
• Active surveillance monitoring for low-risk prostate cancer
• Assessment after treatment for prostate cancer

How to Prepare

• Bowel preparation: Some centres recommend a micro-enema or low-residue diet before the scan to reduce rectal gas artefact.
• Fasting: A light fast of 2 to 4 hours may be advised.
• Avoid ejaculation: Some guidelines recommend abstaining for 48 to 72 hours before the scan, as ejaculation can affect prostate appearance on MRI.
• Metal screening: Standard MRI safety checks.
• Previous results: Bring any previous PSA results, biopsy reports, or imaging.

What to Expect During the Scan

1. Positioning: Lie on your back. A body coil is placed over the pelvis. Some centres use an endorectal coil (inserted into the rectum) for enhanced image quality, although this is becoming less common with modern scanners.
2. Duration: 30 to 50 minutes.
3. Multiple sequences: Multiparametric MRI includes T2-weighted, diffusion-weighted (DWI), and dynamic contrast-enhanced (DCE) sequences.
4. Contrast: Gadolinium contrast is typically administered partway through the scan.
5. After: Resume normal activities immediately.

How Much Does a Prostate MRI Scan Cost?

Private prostate MRI scans in the UK typically cost between £400 and £900. Lola Health offers transparent pricing with expert uroradiologist or consultant radiologist reporting.

Prostate MRI and Blood Testing

Blood tests are core to prostate health assessment:

• PSA (prostate-specific antigen): The primary blood test for prostate cancer screening. Elevated PSA often triggers a prostate MRI referral. Lola Health offers PSA testing as part of our men's health checks.
• Free-to-total PSA ratio: Helps distinguish between cancer and benign causes of PSA elevation.
• Full blood count: Baseline health assessment and identification of anaemia that may be associated with advanced disease.
• Kidney function (eGFR, creatinine): Important for contrast administration and because prostate enlargement can affect urinary tract function.
• Testosterone: Low testosterone levels may be relevant in prostate cancer management and overall male health.
• Liver function: Relevant for staging purposes if metastatic disease is being investigated.

Start with a Lola Health blood test to check your PSA (total and free), testosterone, and kidney function. If results suggest further investigation, a prostate MRI can provide the structural detail your blood results can't show. Peak Insights 70 covers these markers across 70 biomarkers.

Frequently Asked Questions

Can a prostate MRI detect cancer?

Yes. Multiparametric MRI is the most accurate non-invasive method for detecting clinically major prostate cancer. It uses the PI-RADS scoring system (1-5) to categorise suspicion level.

Do I need a biopsy if my MRI is normal?

A low PI-RADS score (1-2) greatly reduces the likelihood of clinically major cancer. Your urologist will advise based on the MRI findings alongside your PSA and clinical history.

Is the scan uncomfortable?

The scan itself is painless. If an endorectal coil is used, there may be mild discomfort during insertion, but this is brief.

Do I need a referral?

No. Book directly through Lola Health.

How soon will I get results?

Typically within a few working days from a specialist radiologist.

At what age should I consider a prostate MRI?

Prostate cancer risk increases with age, particularly after 50 (or 45 if you are of African-Caribbean descent or have a family history). PSA testing is recommended as a first step, with MRI considered if PSA is elevated.

Can MRI replace prostate biopsy?

MRI can help avoid unnecessary biopsies by identifying men who are unlikely to have clinically major cancer. However, when suspicious areas are found, biopsy remains necessary for definitive diagnosis.
