One of the problem of whole heart coronary MRA is the prolongation of acquisition time. It is caused for degrade image quality. However, the radial sampling technique is able to obtain image of inconspicuous artifact such as aliasing and motion; furthermore, the sequence is possible to reduce scan time by understate data sampling. Hence the zoomed whole heart coronary MRA with pseudo golden angle radial sampling was improved image quality without extend scan time.
