Cerebral
aneurysm is a high risk factor for cerebrovascular events. Although DSA is the standard
reference, MRA is an alternative and repeatable technique for patients,
especially those who are renal dysfunction. Hence, we introduce a novel MRA
technique using zero TE and continuous ASL sequence on a clinical 3.0T MR
scanner. 10 patients were recruited receiving zTE and TOF MRA acquisitions. Image
quality and delineation of aneurysm were compared between two techniques. The results
indicated that zTE possesses superiority than TOF, and shows a promise as being
a replacement for TOF in imaging of cerebral aneurysm.
