MPRAGE imaging at 7T allows for the generation of
intracranial angiographies (MRA). This is promising as
TOF at 7T is limited owing to SAR-constraints. To be of
clinical value, however, 7T MPRAGE-MRA has to offer at
least the diagnostic level of the highest current
clinical standard, e.g. TOF-MRA at 3T. In the present
work, we analyzed 16 patients with cerebrovascular
disease (stroke and moya-moya-disease) at 3T and 7T. We
could show that 7T MPRAGE offers a diagnostic quality
comparable to 3T TOF. This is promising, as
high-resolution anatomic and vascular imaging could be
performed using a single sequence at 7T.
