Clinical Trial Summary

Multiparametric magnetic resonance imaging (mpMRI) is now widely used to risk stratify men with a suspicion of prostate cancer and identify suspicious regions for biopsy. Advanced MRI techniques have emerged which seek to improve this characterisation and could predict biopsy results non-invasively before men undergo biopsy. Before these techniques are translated clinically, robust histological and clinical validation is required. This study aims to clinically validate advanced MRI techniques in a cohort of men suspected with prostate cancer. Histological analysis of men undergoing biopsy, +/- prostatectomy will be used for biological validation of VERDICT; Vascular and Extracellular Restricted Diffusion for Cytometry in Tumours and Luminal Water imaging (LWI). In particular, prostatectomy specimens will be processed using 3-D printed patient-specific moulds to allow for accurate MRI and histology mapping.
