EPI-DWI images with Compressed SENSE (EPICS) using high b-values showed higher SNR and ADC values than
EPI-DWI images with SENSE. High b-value EPICS will play a vital role to diagnose
various brain diseases.
Figure 1. SNR measurement. SNR of white matter is calculated by mean SI of white matter (ROI 1) on EPI-DWI (A) and SD of background signal intensity (ROI 2) on noise image (B). SNR: signal-to-noise ratio, SI: signal intensity, ROI: region-of-interest, SD: standard deviation

images with Compressed SENSE (A) and EPI-DWI images with SENSE (B) . Higher
b-value EPI-DWI images with both Compressed SENSE and SENSE show lower image
quality. However, noise-like artifacts on EPI-DWI images with SENSE is more
prominent than on EPI-DWI images with Compressed SENSE.
