The role of 4D MRA with keyhole and view-sharing at 3.0T in the diagnostic work-up of cerebral arteriovenous malformations: a prospective intra-individual study

Introduction Time resolved MRA is a promising technique in the diagnostic assessment of many supraaortic vascular pathologies including the diagnosis and follow-up of cAVM; however, due to its limited spatial and temporal resolution as compared to DSA, it suffers from shortcomings in the detailed characterization of cAVM, especially with respect to hemodynamic considerations (1). Previous studies allowed for temporally accelerated imaging at preserved high spatial resolution by a combination of keyhole (2,3), CENTRA (4), parallel imaging (5), partial Fourier, and alternating view-sharing (6). The current study was carried out to compare high temporal resolution 4D MRA in the entire diagnostic work-up of cAVM including preand post-operative assessment.
