improved blood suppression methods are promising for accurate imaging by
dual-inversion 3D FSE imaging sequence with real-time navigator technology
for high-resolution, free-breathing black-blood CMRA, delineation of coronary
artery by echoplanar imaging. In general, in future, high-resolution MRA seems
well suited to 3.0 T MR field strength since spatial resolution is often limited by
S/N at 1.5 T. Initial feasibility of CMRA for intracranial and cervical studies is en-
couraging. 3.0 T and higher magnetic field scanners with superior field strength
for 3DTOF and is extremely promising for 3DTOF and CMRA. The CMRA has
advantages of shorter scan time and better depiction of slow flow hence it was
the attention in last decade with combination of other modalities.
