diagnostic performance of 18f-psma-1007 pet/ct in suspected prostate cancer patient

Conditions: Prostate Cancer; Prostate Neoplasm

Summary: the diagnostic tools for detecting patients with early prostate cancer are limited due to poor diagnostic performance. the positron emission tomography (pet) combination with the diagnostic radiopharmacy is a non-invasive tool to provide the molecular imaging of the whole body and offer more comprehensive physiological information and then can raise the diagnostic performance. prostate-specific membrane antigen (psma)-targeting pharmaceuticals have been regarded as the most promising diagnostic tool to diagnose patients with prostate cancer. currently, the 18f-psma-1007 as psma-targeting 18f-radiolabeled pharmaceuticals have developed and successfully used in patients with intermittent- and high-risk prostate cancer or recurrent prostate cancer. the study aims to understand the diagnostic performance of 18f-psma-1007 pet/ct in different-stage prostate cancer patients by initiating the first multicenter clinical trial of 18f-psma-1007 in taiwan.
