One of the problems of whole heart coronary MRA is the prolongation of acquisition time, and the radial sampling technique is able to obtain the image of inconspicuous artifacts such as aliasing and motion. Furthermore, the improved sequence of 3D d-Vane is possible to adopt a self-navigator without extend scan time. Hence the small FOV whole heart coronary MRA with diamond pseudo golden angle radial sampling showed improved efficiency with maintaining the image quality.
