Intra-Aortic Time-Resolved Whole-Brain CT Angiographic Evaluation of an Arteriovenous Malformation

This is the first documented case of time-resolved (4D) intra-aortic whole-brain CTA reported in the literature for a newly diagnosed AVM. This was performed simultaneously as part of a catheter cerebral angiography with both planar and CT imaging, in the hybrid interventional radiology/CT suite. The described technique is unique in that intra-aortic injection of diluted contrast was utilized to obtain the time-resolved CTA image of the whole brain.
