Although steady state free procession (SSFP) has been
accepted as the method of choice for coronary magnetic
resonance angiography (CMRA) at 1.5 T, whether SSFP is
suitable for CMRA at a high field strength remains
uncertain. We conducted a feasibility study
three-dimensional free breathing non contrast CMRA using
between SSFP and fast gradient-echo imaging (FGRE)
techniques using a 3T commercial scanner. The resulting
measurable improvements in the image quality using
non-contrast SSFP coronary MRA performed using 3T
commercial scanner are likely to lead to more accepted
clinical applications.
