Clinical Trial Summary

This is a single center prospective non-randomized controlled study. The goal of this clinical trial is to figure out whether the combination of PSMA-PET/MR and PHI could add values to each method alone. The main questions it aims to answer are: - Compare the diagnostic value of the combination with each alone and set up a diagnostic model. - Compare the diagnostic value of PSMA-PET/MR+PHI to mpMRI+PHI. - Evaluate the diagnostic value the combination of PHI and PSMA-PET/MR in suspected PCA patients. Patients will experience mpMRI or PSMA-PET/MR and their blood samples will be used to test PSA and p2PSA. Prostate biopsy will be the golden standard.

• Prostate Cancer
• Prostatic Neoplasms

Intervention

Diagnostic Test:
• Prostate biopsy
Targeted guided puncture biopsy guided by B-ultrasound will be performed (in addition to 12-needle system biopsy, if PSMA-PET/MRI or mpMRI indicates a positive lesion, puncture biopsy should be added at the lesion displayed on image, the "12-needle system biopsy+X" scheme).
