摘要

•Parallel imaging is used for DWI of the pancreas but frequently suffers from band-like noise artifacts at high acceleration factors.•L1-regularized SENSE is based on the CS framework concepts and can effectively eliminate noise artifacts using the same scan parameters.•Implementation of L1-regularized SENSE improves image quality and robustness of ADC values in DWI of the pancreas.
