Prostate MRI Scan — Early Detection

Multi-parametric MRI (mpMRI) is the most accurate non-invasive way to assess the prostate gland. It's better than PSA blood tests alone, better than ultrasound, and it can tell the difference between clinically significant cancers and harmless changes that don't need treatment.

Through Lola Health, you can book a private prostate MRI at 150+ UK centres without a GP or urologist referral. Most people get an appointment within a few days.

What Is a Multi-Parametric Prostate MRI?

A standard MRI takes pictures using one technique. Multi-parametric MRI uses several techniques in the same session, giving the radiologist different types of information about the prostate tissue:

• T2-weighted imaging — Shows the anatomy of the prostate in detail. The radiologist can see the size, shape, and internal structure of the gland.
• Diffusion-weighted imaging (DWI) — Measures how water molecules move through tissue. Cancer cells are packed tightly together, restricting water movement. Areas of restricted diffusion light up on the scan.
• Dynamic contrast-enhanced (DCE) — After a gadolinium contrast injection, this sequence shows how blood flows through the tissue. Cancers tend to have abnormal blood vessel patterns.

These three layers of information are combined to give each suspicious area a PI-RADS score (1-5), where 1 means very unlikely to be cancer and 5 means very likely. This scoring system helps decide whether a biopsy is needed.

Why Choose MRI Over PSA Testing Alone?

PSA (prostate-specific antigen) is a blood test that's been used for decades. The problem is it's not very accurate:

• High PSA doesn't always mean cancer — Benign enlargement (BPH), infection, and even vigorous exercise can raise PSA. About 75% of men with a raised PSA who get biopsied don't have cancer.
• Normal PSA doesn't rule out cancer — About 15% of men with normal PSA do have prostate cancer.
• PSA can't tell you location or significance — Even if PSA is raised, it doesn't tell you where the cancer is or whether it's the type that needs treatment.

Multi-parametric MRI addresses all of these problems. It shows you exactly where any suspicious areas are, how large they are, and gives a PI-RADS score indicating how likely they are to be significant. NICE now recommends mpMRI before biopsy for exactly this reason.

The ideal approach: get both PSA and MRI. Use PSA as an initial indicator, and MRI to provide the detailed picture.

Who Should Consider a Prostate MRI?

• Men over 50 — Prostate cancer risk increases significantly from 50 onwards. The NHS doesn't routinely screen for prostate cancer, so private screening fills that gap.
• Men over 45 with family history — If your father or brother had prostate cancer, your risk is 2-3x higher. Black men also have higher risk and should consider screening from 45.
• Raised or rising PSA — If a blood test has shown raised PSA, mpMRI can clarify whether there's a visible abnormality or whether the PSA rise is likely benign.
• Previous negative biopsy — If you've had a biopsy that came back negative but PSA remains high, MRI can look for lesions in areas the biopsy may have missed.
• Active surveillance — Men on active surveillance for low-grade prostate cancer use MRI to monitor for any changes.
• Urinary symptoms — Difficulty urinating, frequent night-time urination, weak flow — while usually caused by benign enlargement, MRI can rule out cancer as a cause.

Pricing

Option	Price
Prostate MRI (standalone)	£449
Full Body Base MRI (includes pelvis/prostate area)	£1,399
Full Body Comprehensive MRI	£2,299

A standalone prostate MRI is a focused, targeted scan. If you want broader screening alongside prostate imaging, a full body package covers the rest of your body in the same session.

What Happens During the Scan

1. Preparation — You may be asked to use a micro-enema (small disposable enema) about an hour before the scan to clear the rectum. This reduces motion artefact and improves image quality. We'll send instructions when you book.
2. Check-in — Arrive 15 minutes early. Complete the safety questionnaire, change into a gown.
3. The scan — You lie on your back on the scanner table. The scan focuses on your pelvis and prostate area. You'll need to stay still. It's loud — ear plugs provided.
4. Contrast injection — Partway through, you'll receive a gadolinium contrast injection through a cannula for the dynamic contrast-enhanced sequences.
5. Duration — About 30-40 minutes.
6. After — You can drive home and carry on normally. No recovery time.

Understanding Your Results — PI-RADS Scores

The radiologist assigns a PI-RADS score to any area of interest:

PI-RADS Score	What It Means	Usual Next Step
1	Very low suspicion — very unlikely to be clinically significant cancer	Routine follow-up only
2	Low suspicion — unlikely to be clinically significant cancer	Routine follow-up, possibly repeat MRI in 12-24 months
3	Equivocal — uncertain whether clinically significant cancer is present	Discuss with clinician; may need targeted biopsy or close monitoring
4	High suspicion — likely to be clinically significant cancer	Targeted biopsy usually recommended
5	Very high suspicion — very likely to be clinically significant cancer	Targeted biopsy strongly recommended

Scores of 1 or 2 are reassuring. Score 3 warrants discussion. Scores 4 or 5 typically lead to a targeted biopsy — but critically, MRI-guided biopsies are more accurate than random biopsies because the radiologist has already shown the urologist exactly where to look.

Pair with PSA Blood Testing

The best approach to prostate screening combines both PSA and MRI:

• PSA — Quick, cheap, gives a baseline number. Good for tracking changes over time.
• MRI — Shows exactly what's happening in the gland. Identifies and scores any lesions.
• Together — Rising PSA combined with a PI-RADS 4 lesion on MRI gives the urologist a clear picture. Normal PSA with a clean MRI is very reassuring.

Our Peak 70 blood test covers 70+ biomarkers. PSA can be added as a supplementary marker.

Common Questions

Do I need a referral?

No. Book directly through Lola Health. Every booking is reviewed.

Is a prostate MRI uncomfortable?

No. You lie on your back for about 30-40 minutes. There's no rectal probe — modern multi-parametric MRI uses an external coil. The only invasive element is the contrast injection, which is a standard cannula in your arm.

How does this compare to a TRUS biopsy?

A TRUS (trans-rectal ultrasound) biopsy takes random tissue samples — it can miss cancers and detect clinically insignificant ones. MRI-first means you only get biopsied if the scan shows something suspicious, and the biopsy can be targeted to the exact area. This reduces unnecessary biopsies by about 25-30%.

My PSA is normal — should I still get an MRI?

About 15% of men with normal PSA have prostate cancer. If you have risk factors (family history, Black ethnicity, age over 50), MRI adds reassurance that PSA alone can't provide.

How often should I have a prostate MRI?

For general screening, every 2-3 years from age 50 (or 45 with risk factors). If you're on active surveillance, your urologist will advise — usually annually.

Is gadolinium contrast safe?

Yes, for the vast majority of people. Allergic reactions are very rare (about 1 in 10,000). Gadolinium is cleared through your kidneys within 24 hours. If you have significantly impaired kidney function, alternatives will be discussed with you.
