Cognitive magnetic resonance imaging-ultrasound fusion transperineal targeted biopsy combined with randomized biopsy in detection of prostate cancer

Figure 1 A schema for the transperineal template-guided cognitive magnetic resonance imaging-ultrasound fusion TBx plus randomized biopsy strategy. A: Axial T2-weighted imaging (T2WI); B: Axial diffusion-weighted imaging (DWI) (orange arrow); C: The same plane on transrectal ultrasound imaging with magnetic resonance imaging (MRI); D: The procedure for biopsy. A lesion suspicious for prostate cancer was found with low signal on T2WI and high signal on DWI. The area within the red ellipse was considered the corresponding lesion with MRI identified by cognition and would be recognized as the targeted lesion for biopsy.
