We evaluated the feasibility of optimal gating method and imaging parameters for Single-Shot Turbo Spin Echo (ssTSE) diffusion weighted image (DWI). As a result, The Peripheral pulse gating (PPG) synchronization method was significantly higher in visual scoring than that of the ECG synchronization method (p=0.02) and ssTSE-DWI using SENSE-factor 4.0 brought about the best image quality. Refocusing Flip Angle (RFA) tended to be higher in images with higher visual score. Visualizing cardiac DWI was feasible under above conditions. In conclusion, it is expected that ssTSE-DWI using PPG has a possibility to detect abnormal signal from myocardium by non-contrast MRI.
