Steiger P, et al. – In this retrospective study, authors intended to evaluate whether diffusion–weighted magnetic resonance imaging (DW–MRI) allows physicians to determine the severity of histopathologic findings in biopsies of renal allograft patients with deteriorating renal function. It was considered that combined qualitative and quantitative DW–MRI might allow physicians to determine the severity of histopathologic findings in biopsies of a high number of kidney transplant patients.
