Investigation of Liver Diffusion Kurtosis Imaging and Perfusion Effect

Yuriko Suzuki¹, Marc Van Cauteren¹

Diffusion Kurtosis Imaging (DKI) is a method to study the deviation of water diffusion from Gaussian distribution, which has been applied mostly to study neural tissue characterization and brain diseases. The aim of study was to investigate how the selection of maximum and minimum b-value affected the liver DKI analysis, and to assess the feasibility of liver DKI in reasonable scan time. Our study has shown relatively good results even with maximum b-value of 1,500 s/mm2, which is smaller than one used in the brain, and would make easier to apply clinical cases.
