Improved specificity with 68Ga PSMA PET/CT to detect clinically significant lesions “invisible” on multiparametric MRI of the prostate: a single institution comparative analysis with radical prostatectomy histology

Abstract

PURPOSE: Positron emission tomography (PET) for prostate-specific membrane antigen (PSMA) represents a promising method for prostate cancer diagnosis and staging. Comparisons of PSMA-based tumour characterisation to multiparametric MRI (mpMRI) are limited, hence this study sought to compare the diagnostic accuracy of

METHODS: A retrospective cohort study of consecutive patients who underwent pre-operative mpMRI and

RESULTS: Fifty-eight patients (median age 65.5 years, median PSA 7.35 ng/mL) underwent RP, resulting in a high-risk cohort (≥pT3 69%). Sensitivities for identification of index lesion, bilateral and multifocal disease were 90%, 21%, 19% for mpMRI and 93%, 42%, 34% for
