Diffusion kurtosis MRI versus conventional diffusion‐weighted imaging for evaluating inflammatory activity in Crohn's disease

Purpose To assess the efficacy of diffusion kurtosis imaging (DKI) and to compare DKI‐derived parameters with that of conventional diffusion‐weighted imaging (DWI) for grading the inflammatory activity of Crohn's disease (CD). Materials and Methods In all, 38 patients with CD underwent 3T magne...

Zusammenfassung:	Purpose To assess the efficacy of diffusion kurtosis imaging (DKI) and to compare DKI‐derived parameters with that of conventional diffusion‐weighted imaging (DWI) for grading the inflammatory activity of Crohn's disease (CD). Materials and Methods In all, 38 patients with CD underwent 3T magnetic resonance enterography (MRE) with DKI (b values of 0–2000 s/mm2). The inflammatory activity of the bowel segments was graded by magnetic resonance index of activity (MaRIA) as inactive (
