We achieved well visualization of the cardiac diffusion-weighted imaging with 2nd moment nulling diffusion gradient. The purpose of this study was to assess the IVIM of heart using 2nd moment nulling pulse and high b-value. The ADC and f using 2nd moment nulling pulse were significantly lower than using 1st moment nulling pulse. Thus, 2nd moment nulling pulse is insensitive to phase dispersion caused by pulsatile motion. In conclusion, we achieved improvement of heart IVIM.
