Pharmacokinetic analysis of data generated using Dynamic-Contrast-Enhanced MRI (DCE-MRI) has proven to be a valuable tool in the evaluation of the vascular pathophysiology of prostate adenocarcinoma. With improved hardware, multi-slice parametric mapping has become feasible and could provide valuable insight to complement conventional T2*-weighted images. In this study multi-slice parametric mapping was performed with DCE-MRI data using both the standard model (SM) and the first generation shutter-speed model (SSM1). Parametric maps were then compared with biopsy results.
