Bi-Parametric Prostate MRI

A specialist prostate MRI scan performed without IV contrast, using T2-weighted and diffusion-weighted imaging sequences to evaluate the prostate gland for suspicious lesions. A non-invasive screening option for men concerned about prostate health, particularly those with elevated PSA or a family history of prostate cancer.

Bi-parametric prostate MRI has emerged as an increasingly popular screening tool for men who want to investigate prostate health without undergoing an invasive biopsy as a first step. The scan uses two MRI sequences — T2-weighted imaging to visualise prostate anatomy and diffusion-weighted imaging to detect areas of restricted water diffusion that may indicate clinically significant lesions. This approach avoids the need for IV contrast injection, making the scan quicker, more comfortable, and suitable for patients who prefer to avoid gadolinium or have contraindications to contrast agents. Research evidence supports bi-parametric MRI as having comparable sensitivity to the full multi-parametric protocol for detecting clinically significant prostate cancer, while offering a shorter scan time and lower cost. The scan is typically chosen by men with elevated or rising PSA levels who want imaging before committing to a biopsy, those with a family history of prostate cancer seeking proactive screening, and men who want a baseline prostate image for future comparison. For cases where the bi-parametric scan identifies areas requiring further characterisation, the multi-parametric protocol with contrast is available as a step-up option.
