The purpose of this study is to assess the fractional anisotropy (FA) of heart using ECG gating and second moment nulling pulse which is intrinsically insensitive to motion. The FA at motion correction (MC) gradient was significantly higher than at acceleration motion correction (aMC) gradient, therefore, cardiac motion artifact resluts in an overestimation of FA. In conclusion, the use of second order motion correction gradient enables the quantification of FA at heart and has the potential to contribute to clinical cardiac imaging.
