FOLH1 and Familial prostate cancer: On patient-based level, network meta-analysis reveals that for numerous tracers, 68Ga-PSMA PET/CT has the highest superiority index, followed by 18F-NaF, 11C-choline, 18F-choline, 18F-FDG, and 18F-fluciclovine PET/CT; for the parameters of MRI, higher magnetic field strength, multisequence, more imaging planes, and MRI with DWI will increase the diagnostic value for bone metastasis in prostate cancer patients.
