Robot-assisted Magnetic Resonance Imaging-ultrasound Fusion Transperineal Targeted Biopsy.

Objective: To demonstrate the key steps to perform robot-assisted magnetic resonance imaging-ultrasound fusion transperineal prostate biopsy.

Materials And Methods: Men with suspicion of prostate cancer underwent 3-Tesla multi-parametric MRI and were assigned a Prostate Imaging Reporting and Data System v2 score (PI-RADS). The prostate outline and suspicious lesions were marked by our radiologist using our software to produce a 3-dimensional prostate MRI model.

Limitations of overlapping cores in systematic and MRI-US fusion biopsy.

Objectives: To evaluate the clinically-significant prostate cancer (csCaP) detection rate of systematic (SBx) vs. targeted biopsy (TBx), after accounting for the overlapping systematic cores within the MRI regions of interest.

Materials And Methods: We identified 398 consecutive men who underwent both transperineal systematic and targeted biopsy between January 2015 to January 2019.
