Improvement of visualization of cardiac wall in diffusion-weighted imaging using cardiac triggering and acceleration motion correction

Introduction Diffusion-weighted imaging (DWI) of the body has shown the clinical utilities for detection of tumor and for the evaluation of pathologic conditions. However, the cardiac DWI often results in significant signal loss and poor visibility caused by pulsatile motion even though the low b-value and cardiac triggering are used [1]. The purpose of this study was to assess the visualization of cardiac wall in cardiac triggered DWI using motion correction (MC) and acceleration motion correction (aMC) (Fig.1) [2].
