Post-MRI transrectal micro-ultrasonography of transition zone PI-RADS & gt; 2 lesions for biopsy guidance

ConclusionMRI-targeted transrectal microUS is effective to detect TZ-sPCa. TRUS-MRI image fusion helps overcome limitations due to TZ tissue heterogeneity.Key PointsmicroUS can visualize the majority of MRI-detected PI-RADS> 2 TZ lesions (sensitivity = 83%).Interreader agreement of MRI-directed microUS in the detection of TZ lesions appears excellent (kappa = 0.88).In 77% of PI-RADS> 2 TZ lesions, biopsy was performed under microUS visual control. MRI fusion system was only used to overcome limitations due to tissue heterogeneity of benign prostatic hyperplasia.
