Steps for mpMRI and TRUS fusion guided targeted prostate biopsy and whole-gland prostatectomy pathology in a typical patient with negative biopsy two years ago but elevated prostate-specific antigen. A-C, The lesion (red arrow) was detected in different mpMRI sequences and was scored as “probably malignant” (score 4 of 5). D-E, mpMRI data was loaded into the biopsy system and suspicious region (greeb circle) was marked on high resolution transversal T2 W sequences before biopsy. Then, the targeted biopsy started using the free-hand transperineal technique guided by mpMRI and TRUS fusion images (red arrow). F, Targeted cores revealed Gleason 3 + 4 tumor in the lesion (90% core involvement). Whole-gland pathology was performed after prostatectomy and the index lesion (black circle) had the same pathology result with targeted biopsy
