Synopsis

This study demonstrates that DWI with MUSE and RPG correction significantly reduces the geometric distortions and results in increased overall image quality without altering ADC in a pediatric patient population, compared to single-shot EPI. This improvement was confirmed both through quantitative and qualitative analysis.
