High b-value single-shot echo planar diffusion-weighted imaging (EPI-DWI) has been expected to provide more detail information about brain structure and diseases. However, higher b-value causes lower image quality due to an increase in noise-like artifacts. Compressed SENSE (C-SENSE), which is a combination of compressed sensing and parallel imaging technique: SENSE is an accelerating scan technique, which includes noise reduction methods. In this study, we revealed that EPI-DWI images with C-SENSE using high b-values (b:1000, 2000, 3000, 4000, 5000 s/mm2) showed higher SNR and ADC values than EPI-DWI images with SENSE.
