Development of Clinical Assessment Technique Using Multi-radiotracer PET/MR in Prostate Cancer

To establish the optimal imaging technique of PET/MR using multiple radioactive tracers for prostate cancer

• Recruiting 30 patients with prostate cancer ahead to radical prostatectomy
• PET/MR using 18F-choline with dedicated prostate MRI in all patients
• PET/MR using 18fluoride(F)-fluorodeoxyglucose(FDG)in all patients after 2-7 days
• PET/CT using 18F-FDG in all patient immediate after 18F-FDG PET/MR
• outcome assessment: comparison of scan time, image quality, tumor detection rate, standardized uptake values of lesions
• establishing optimal imaging technique for prostate PET/MR

To establish the imaging biomarker using PET/MR for clinical assessment of prostate cancer

• comparison of findings on PET/MR, MRI and PET/CT with pathological mapping after radical prostatectomy
• outcome assessment: accuracy of PET/MR for localization and staging of prostate cancer compared with MRI only and PET/CT only

To establish the imaging biomarker using PET/MR for early detection of recurrent prostate cancer
