In-bore 3.0-T Magnetic Resonance Imaging-guided Transrectal Targeted Prostate Biopsy in a Repeat Biopsy Population: Diagnostic Performance, Complications, and Learning Curve.

Objective: To evaluate the diagnostic performance and complication rate of the in-bore magnetic resonance imaging-guided transrectal targeted prostate biopsy (MRGB) in a repeat biopsy population on the basis of a nearly 4-year learning curve (2014-2017).

Materials And Methods: A total of 142 consecutive males with previous biopsies and persistent suspicion of prostate cancer (PCa) due to high prostate-specific antigen level initially underwent MRGB in the case of prostate imaging reporting and data system (PI-RADS) 3-5 lesions. Cancer detection rate (CDR), number and length of cores, biopsy time, operator experience, complications, and prediction of clinically significant (cs) PCa (Gleason score ≥7) were investigated.

Prostate-specific Antigen Parameters and Prostate Health Index Enhance Prostate Cancer Prediction With the In-bore 3-T Magnetic Resonance Imaging-guided Transrectal Targeted Prostate Biopsy After Negative 12-Core Biopsy.

Objective: To assess prostate cancer (PCa) detection and prediction by combining the in-bore magnetic resonance imaging-guided transrectal targeted prostate biopsy (MRGB) with prostate-specific antigen (PSA) parameters and the Prostate Health Index (PHI) in case of negative 12-core standard biopsy.

Materials And Methods: A total of 112 men (2014-2016) underwent 3-T multiparametric magnetic resonance imaging and subsequent MRGB of Prostate Imaging-Reporting and Data System (PI-RADS) lesions 3-5. Ancillary PSA parameters (PSA ratio [%fPSA] and PSA density [PSAD]) and the PHI and PHI density (PHID) were recorded.
