Cardiac diffusion imaging is of increasing interest in
studying myocardial disease, both acute and chronic.
This study compares diffusion metrics (ADC and FA) from
and reproducibility of stimulated echo cardiac diffusion
with two different readouts, EPI and SSFP, in normal
volunteers. We obtain similar ADC (EPI: 1.090.09mm
2
/s;
SSFP: 1.140.11mm
2
/s) and FA (EPI: 0.470.06;
SSFP: 0.0410.04) with the two sequences. . The EPI
method has better reproducibility due to its higher SNR.
