Brief Summary:
The Chinese Cerebral Aneurysms Survey is a continuing prospective study to evaluate the effectiveness of unenhanced three-dimensional time-of-flight magnetic resonance angiography 3D-TOF-MRA with volume rendering VR at 3-T in the detection of intracranial aneurysms
Detailed Description:
Recent yearsthree-dimensional time-of-flight MRA 3D-TOF-MRA has become a useful contrast-free method for observing intracranial vessels and is widely utilized as a screening examination for intracranial aneurysms The studies available in Medline show mixed resultsSome of these studies just included MRIMRA in the analysis which have a high rate of false-positives and are unreliable and some were lack of control ruptured aneurysm precise numbers of false-positive results standard images process and review or corroborative IADSA in some patients Furthermore most previous studies included small sample size with aneurysm detection at 05-T or 15-T MR Thus these results have been inconclusive because of certain pitfalls in these studies
Since 2007 we have conducted a clinical study to objective detection of intracranial aneurysms in our routine diagnostic work-up of intracranial aneurysms by our neuroradiologists using a standard procedure with 3D-TOF-MRA with VR at 3T The investigators want to establish the quality data to prospectively compare 3D-TOF-MRA with VR at 3T vs 3D-RDSA in the diagnosis of intracranial aneurysms in a largest cohort of patients and test it accuracy in screening for suspected patients
