PSMA PET/MR radiomics to improve postsurgical Gleason score prediction in prostate cancer

Ziel/Aim Gleason score (GS) is an important parameter for patient management in primary prostate cancer (PC), but biopsy-based GS (bGS) underestimate the more reliable postsurgical GS (psGS), obtained after radical prostatectomy (RP). In a previous work, we showed that radiomics from prostate-specific membrane antigen (PSMA)-targeted PET and Apparent Diffusion Coefficient (ADC) maps can predict psGS. In this work, we investigate the performance...
