68Ga-P16-093 is a novel radiotracer targeting PSMA. Previously, we conducted multiple studies confirming the clinical application of 68Ga-P16-093 PET/CT. However, multi-parametric magnetic resonance imaging (mpMRI) still holds a dominant position in the imaging diagnosis of prostate cancer. In this study, we will further evaluate the diagnostic performance of 68Ga-P16-093 positron emission tomography (PET/CT or PET/MRI) in newly diagnosed and untreated prostate cancer patients, with a head-to-head comparison to mpMRI.
