One of the problems of whole heart coronary MRA using bSSFP sequence at 3.0T is banding artifacts, caused by a long TR due to SAR limitations, resulting in degradation of image quality. A non-selective radio frequency (RF) pulse (e.g. block or hard pulse) enables to shorten the TR that leads to to reduce the banding artifacts. Hence whole heart coronary MRA using the bSSFP with non-selective RF pulse was improved image quality at 3.0T.
