Recent studies have demonstrated that microultrasonography (microUS) is as effective as magnetic resonance imaging (MRI) combined with ultrasound (US) fusion in detecting clinically significant prostate cancer. A randomized clinical trial published in JAMA compared microUS-guided biopsies with MRI/US fusion-guided biopsies in biopsy-naive men. The results indicated that microUS-guided biopsy was noninferior to MRI/US fusion-guided biopsy for detecting Gleason Grade Group 2 or higher prostate cancer, suggesting that microUS may serve as a viable alternative to MRI for image-guided prostate biopsies.
Further supporting these findings, a study reported by The ASCO Post highlighted that microUS identified prostate cancer as effectively as MRI-guided biopsy, with comparable detection rates across different trial arms. This suggests that microUS could potentially streamline the biopsy process by providing real-time imaging without the need for MRI, thereby reducing costs and improving accessibility for patients undergoing prostate cancer evaluation.
