TRUS biopsy (TRUS-Bx) is the standard of care for prostate cancer diagnosis but has several limitations. Multiparameteric MRI and MRI guided biopsy (MRGB) show considerable added benefits with better disease detection and stratification. The purpose of this study is to evaluate the role of in-bore MRI guided biopsy in patients with positive TRUS-Bx. 40 patients with 71 TRUS-Bx positive lesions were analyzed for cancer detection rate, false negative rate, and Gleason score upgrade by MRGB. MRGB showed 65% cancer detection rate, 35 % false negative rate, and upgraded disease status in 40% of the whole sample
