Cardiac diffusion-weighted imaging (DWI) often results
in signal loss and poor visibility even though the
cardiac triggering is used. The purpose of study is to
assess the visualization of cardiac wall in cardiac
triggered DWI using motion correction (MC) and
accelerate motion correction (aMC). Muscle normalized
signal intensity at aMC DWI is significantly higher than
MC DWI and cardiac triggered DWI in each b-value of 200,
400, 600, and 800s/mm2. Visualization of cardiac wall is
improved at aMC DWI even if the high b-value is used.
DWI with aMC may enable to assess water molecular change
in myocardial infarction.
