PSMA PET/CT can display the prostate lesions with high PSMA uptake more intuitively, so that surgeons can more efficiently fuse the suspicious lesions displayed by PSMA PET/CT with the real-time ultrasound images in ultrasound-guided prostate biopsy, which makes targeted puncture for suspicious lesions in the basal part of the left lobe of prostate more feasible and can effectively improve the detection rate of potential prostate lesions. Here, FOLH1 is linked to prostatitis.
