When you’re facing questions about your prostate health, clarity matters. In recent years, the prostate MRI scan – especially multi‑parametric MRI (mpMRI) – has become central to early, accurate diagnosis. An MRI scan before prostate biopsy can help your clinical team decide whether a biopsy is needed at all, and if it is, where to look first. In this guide, we explain why an MRI before prostate biopsy is recommended, how it works, and how Santis integrates MRI into a streamlined, compassionate diagnostic pathway.

Understanding How Prostate Cancer Is Usually Diagnosed
Traditionally, men moved from a raised PSA (prostate‑specific antigen) test and clinical examination straight to biopsy. At Santis, however, our normal practice is to arrange an MRI scan prior to any prostate biopsy, because imaging helps decide whether a biopsy is needed and, if it is, exactly where to sample.
While biopsy remains a vital tool, going straight in has drawbacks: it can miss clinically significant cancers, detect very low‑risk disease that may never cause harm, and create understandable anxiety. That’s why imaging now plays a much larger role. A prostate MRI scan offers a more detailed picture of the gland and surrounding tissues – supporting better triage and MRI for prostate cancer detection that focuses attention on what matters most. MRI findings are summarised using PI‑RADS or Likert (a 1–5 score of suspicion); scores of 3–5 usually prompt targeted biopsy when the examination is otherwise normal.
What Is an MRI Scan Before a Prostate Biopsy?
An MRI scan before a prostate biopsy is a non‑invasive imaging test that uses a strong magnetic field and radio waves to generate high‑resolution images of the prostate. Doing the scan before biopsy also avoids “biopsy artefact” – small areas of bleeding from biopsy needles that can obscure details on a later MRI – another reason we sequence tests this way.
There’s no radiation, and the scan is painless – simply lie still while the scanner takes pictures. The result is a detailed map of the prostate that helps your specialist judge whether a biopsy is needed. If it is, the MRI before prostate biopsy findings guide the plan so that the right areas are sampled.
At Santis, MRI is integrated early in the pathway wherever appropriate, with reporting by experienced prostate radiologists and rapid review by our urologists. This means less waiting, fewer unnecessary procedures, and faster answers.
What Is mpMRI and How Does It Work?
mpMRI prostate cancer imaging combines multiple sequences – looking at the anatomy, how water molecules move in tissue (diffusion), and how blood flows after a contrast injection (perfusion). By layering these views, an mpMRI prostate cancer study can highlight areas that behave suspiciously, while also reassuring when the scan looks completely normal.
Because mpMRI provides such rich information, it is now the preferred prostate MRI scan in most diagnostic settings and is described on our site as the gold standard for diagnosing and staging prostate cancer.
Benefits of Having an MRI Before Prostate Biopsy
Choosing MRI before prostate biopsy offers practical, medical, and emotional benefits:
- Fewer unnecessary biopsies: When the prostate MRI scan shows no suspicious lesions, many men can avoid immediate biopsy and continue with monitoring. At Santis, mpMRI performed upfront avoids unnecessary sampling in roughly 25% of men.
- Better detection of significant disease: If a lesion is present, MRI for prostate cancer detection helps concentrate attention on clinically important changes rather than very low‑risk findings.
- Targeted sampling: When a biopsy is needed, MRI guidance allows the team to target fewer, more precise samples – often improving diagnostic yield while reducing discomfort. We only use transperineal, MRI‑targeted techniques (cognitive or fusion), which focus precisely on PI‑RADS 3–5 areas and carry an infection risk of <1% compared with historical transrectal approaches.
- Reduced side effects and anxiety: Avoiding or minimising biopsies can lower the risk of infection, bleeding, and post‑procedure soreness, and often reduces time spent worrying about unclear results.
At Santis, we prioritise accuracy and comfort. Our surgeons, radiologists and specialist nurses work together so that imaging, consultation and next steps happen in a joined‑up way.
When Is an MRI Recommended?
Your urologist may recommend an MRI scan before a prostate biopsy in several common situations: a raised or rising PSA; an abnormal finding on rectal examination; a strong family history; or persistent urinary symptoms that don’t have another clear explanation. An MRI may also be useful if you’ve had prior biopsies with uncertain results, or to help plan a repeat biopsy more precisely. In some cases – such as very recent imaging, specific medical devices, or particular clinical scenarios – MRI may not be necessary straight away. The decision is individual, and a focused consultation will explore the best timing for you.
How Santis Uses MRI to Improve Early Detection
Santis is dedicated to a clear, evidence‑based pathway that puts you at ease and delivers reliable answers quickly. Following a raised PSA, our pathway is MRI first to decide whether a biopsy is necessary and to map any targets for a transperineal, MRI‑guided biopsy if needed (After a Raised PSA). We use state‑of‑the‑art prostate MRI scan protocols, reported by specialists who read prostate imaging every day. When a biopsy is required, we draw on MRI‑targeted techniques to sample the right areas the first time. This precision not only helps detect important cancers earlier; it also means fewer invasive tests overall and a smoother journey to a decision about treatment.
If cancer is confirmed, you’ll have a calm, detailed discussion of options – from active surveillance to surgical and non‑surgical treatments – so you can make a choice with confidence.

We also outline what to expect in recovery and aftercare should surgery be the right path for you.
Key Takeaways: MRI Before Biopsy Explained
- An MRI scan before a prostate biopsy is now a crucial first step for many men being tested for prostate cancer.
- A modern prostate MRI scan – ideally an mpMRI – improves accuracy, reduces unnecessary biopsies, and guides targeted sampling when needed.
- Santis combines expert imaging, urology, and nursing support to minimise worry, shorten waiting times, and focus quickly on what matters for your health.
