Abstract:
Objective To evaluate the value of 3.0T susceptibility-weighted magnetic resonance imaging (SWI) in the diagnosis of cerebrovascular malformations. Methods Forty-six patients with cerebrovascular malformations, admitted to our hospital fiom May 2008 to December 2010, were examined with a 3.0T MR scanner. All patients were examined with MRI conventional sequences T1WI,T2WI, 3DTOF, and their results were compared with SWI sequence so as to evaluate the value of SWI in the diagnosis of cerebrovascular malformations.Results Twenty-five patients had arteriovenous malformation (AVM), 10 with cavernous hemangioma, 8 with venous malformations, and 3 with telangiectasis in the 46 patients with cerebrovascular malformations. SWI could delineate all the cerebrovascular malformation lesions, especially small lesions, but could not display all supplying artery in AVM. 3DTOF was a better technique in delineating large AVM lesions. Conclusion SWI is much more sensitive in showing small cerebrovascular malformations; and combined with other MR sequences,clear diagnosis of cerebral vascular malformations can be made by SWI.
