The L1-regularized iterative SENSE reconstruction of pancreas single shot DW-EPI significantly reduces the noise band-like artifacts at high acceleration factors and allows more stable and robust ADC quantification (less noise bias) even when including fewer number of averages.
Figure 1: DWI b600 images of the pancreas using the SENSE reconstruction (a) and the L1-regularized SENSE reconstruction (b) in a healthy pancreas. The central noise artifact seen with SENSE (yellow arrowheads) overlapping the pancreas (black star) is significantly reduced in the L1-regularized SENSE.
