PSMA PET/MRI-Guided Prostate Biopsy for PI-RADS ≤3 and Prior Negative Biopsy

The experimental group will undergo PSMA PET/MRI examination. For those with positive PSMA PET/MRI results, a PSMA PET/MRI-TRUS guided prostate targeted biopsy will be performed based on transrectal ultrasound (TRUS) guided transperineal saturation biopsy, targeting the positive lesions. For those with negative PSMA PET/MRI results, only TRUS guided transperineal saturation biopsy will be performed. Clinical and pathological data of the patients will be collected for statistical analysis.

The control group will receive TRUS guided transperineal saturation biopsy. Clinical and pathological data of the patients will be collected for statistical analysis.
