Diffusion and perfusion MR parameters to assess preoperative short course radiotherapy response in locally advanced rectal cancer: a comparative explorative study among parameters derived from standardized index of shape DCE-MRI, intravoxel incoherent motion, and diffusion kurtosis imaging

To assess preoperative Short Course Radiotherapy (SCR) tumor response in locally advanced rectal cancer (LARC) by means of parameters derived from Standardized Index of Shape (SIS) dynamic contrast enhanced (DCE) MRI, Apparent Diffusion Coefficient (ADC), Intravoxel Incoherent Motion and Diffusion Kurtosis Imaging derived parameters by diffusion weighted (DW) MRI.
