Summary: German researchers found that an MRI-first approach for prostate cancer screening is safe and effective, reducing unnecessary biopsies while ensuring early detection of significant cancers.
Key Takeaways
- MRI-First Approach Reduces Need for Immediate Biopsies: Researchers demonstrated that using MRI before recommending biopsies for prostate cancer screening is safe and effective, minimizing unnecessary procedures.
- High Reliability Over Three Years: The study showed that 96% of patients with normal MRI results did not develop aggressive prostate cancer within three years, confirming the approach’s safety and reliability.
- Supports Updated Guidelines for Prostate Cancer Screening: Findings reinforce MRI’s role as a primary diagnostic tool, aligning with European Association of Urology guidelines and promoting more personalized, less invasive patient care.

Researchers at Charité – Universitätsmedizin Berlin have demonstrated that an MRI-first approach for prostate cancer screening is safe and effective, potentially reducing the need for immediate biopsies. The findings, published in JAMA Oncology, reveal that this method poses no additional risk to patients over a three-year period.
Traditional prostate cancer diagnosis begins with a prostate-specific antigen (PSA) blood test. Elevated PSA levels often lead to systematic biopsies, which can cause side effects and infection risks. However, biopsies also risk overdiagnosing slow-growing cancers while missing aggressive forms. In contrast, the MRI-first approach prioritizes imaging to identify abnormalities before recommending biopsies.
Reducing Need for Immediate Biopsies
Charlie Hamm, MD, the study’s first author and a physician at Charité’s Department of Radiology, explains, “We wanted to determine whether men with normal MRI findings could safely skip immediate biopsies and instead enter clinical follow-up. The results confirm this approach is both reliable and safe.”
The study tracked nearly 600 patients with suspected prostate cancer. Those with negative multiparametric MRI (mpMRI) results received regular urological check-ups rather than immediate biopsies. After three years, 96 percent of patients with normal MRI scans had not developed aggressive cancer. Only 4% required further intervention, highlighting the reliability of MRI screening.
“Our findings emphasize the importance of high-quality MRI scans analyzed by trained radiologists,” says Hamm. “With proper monitoring, MRI-based screening reduces unnecessary biopsies while ensuring early detection of significant cancers.”
The European Association of Urology (EAU) guidelines already endorse MRI before biopsies. This study reinforces MRI’s role as a primary diagnostic tool, paving the way for updated recommendations and improved patient care.
