Abstract
In the non-contrast 3D angiography, degradation of image quality caused by change of the cardiac cycle and degradation of image quality depending on the blood flow direction are prevented to provide an MRA image of favorable image quality, which is useful for diagnosis. A pulse sequence of the multi echo type for performing sampling of three-dimensional k-space data in a circular or elliptical shape is employed as the imaging sequence, and gated imaging based on body motion information is performed. Heart rate is monitored during the imaging, delay time DT from a gating signal and data acquisition time AT determined according to the cardiac cycle are calculated, and according to these imaging parameters, sampling trajectory and echo train number of the circular sampling are controlled.
