3.0 T versus 1.5 T MR angiography of the head and neck.
This article presents the advantages and challenges of MR angiography of the intracranial and extracranial cerebral vasculature at 3.0 T with comparative assessment to 1.5 T approaches. The physical basis for the superiority of 3.0 T MR angiography is discussed in the context of evolving technological capabilities afforded by the synergistic advent of higher field scanners, improved coil design, and parallel imaging. This review emphasizes 3.0 T issues related to noncontrast three-dimensional time of flight MR angiography of the intracranial circulation, contrast enhanced three-dimensional time of flight MR angiography of the extracranial cerebral vasculature, and carotid plaque characterization.
