Reflect and diagnosis in the image of 60 cases with cerebral cavernous hemangioma by SWI

[Objective] To investigate the image-features and clinical diagnostic value of cerebral cavernous hemangioma by SWI(Susceptibility Weighted Imaging).[Methods] There were 60 patients with cerebral cavernous hemangioma who were confirmed by operation,DSA and/or MR(MRA,SWI et al) in the group.All of them were scanned by MR which included SET1WI,T2WI,and axis SWI,and 28 cases were additionally scanned with contrast enhancement scan.Paired rank sum test and t-test were used to detect the number and area of lesions.[Results] There were 40 single-cases(66.7%) and 20 multiple-cases(33.3%)in the group.And 316 focuses were detected by SWI,more than that detected by T1WI(64 focuses) and T2WI(77 focuses).It typically showed the sample of popcorn or mulberry-like mixed hypo-and hyperintense with hoop-like hypointensity and halo-like hyperintense on the edge of infection.The areas of lesions are (3.39±5.68) cm2 in SWI and(2.40±5.07) cm2 in T2WI(P0.05).[Conclusion] SWI can detect slimmer lesions than that is examined by routine-MR scan.So it has important clinical value in qualitative and quantitative diagnoses of the cerebral cavernous hemangioma.
