Head-to-head comparison of 68Ga-PSMA-11 PET/CT and mpMRI with histopathology gold-standard in the detection, intra-prostatic localization and local extension of primary prostate cancer: results from a prospective single-center imaging trial.

The role of prostate-specific membrane antigen (PSMA)-targeted PET in comparison to mpMRI in the evaluation of intraprostatic cancer foci is not well defined. The aim of our study was to compare the diagnostic performances of PSMA PET/CT, mpMRI and PSMA PET/CT+mpMRI using 3 independent blinded readers for each modality and with histopathology as gold standard in the detection, intra-prostatic localization and local extension of primary prostate cancer.
