According to the latest data from the China National Cancer Center, prostate cancer has become the most common tumor in the urinary system since 2008. However, conventional imaging techniques including transrectal ultrasound , computed tomography and bone scintigraphy are not sensitive or specific. About 40% of resectable lesions cannot be detected by these techniques. Positron Emission Tomography (PET) provides a valuable tool for the diagnosis and staging of prostate cancer. Recently, prostate-specific membrane antigen (PSMA) as a new novel positron tracer has shown to be effective to detect primary lesions, recurrent and metastatic lesions of prostate cancer. In this prospective study, the investigators will use the most advanced imaging equipments, integrated PET/MR, and PET/CT with prostate cancer-specific imaging agent 68Ga-PSMA and conventional imaging agent [F-18]fluorodeoxyglucose to image patients with or suspected of prostate cancer, the aim is to explore the value of hybrid PET/MR and PET/CT in prostate cancer.

For patients suspected of or diagnosed with prostate cancer, the investigators aim to evaluate the roles of integrated PET/MR and PET/CT in differential diagnosis, detecting primary and metastatic lesions, guilding biopsy, staging and determining treatment plan prior to treatment; for the patients with a history of prostate cancer, the aim is to evaluate the value of integrated PET/MR and PET/CT for treatment response assessment, detection of recurrences and metastatic lesions.
