Analysis of conventional MRI and SWI in diagnosis cerebral cavernous angioma

Objective To evaluate the diagnostic value of SWI in cerebral cavernous angioma by analyzing the imaging findings of conventional MRI and SWI. Methods A retrospective analysis of 18 cases confirmed by operation and pathology in patients with cerebral cavernous angioma of the conventional MRI and SWI image,recording the number of cerebral cavernous angioma in the conventional MRI T2 WI,T1WI and SWI,and measuring the size of the lesion. Results 18 cases of cerebral cavernous angioma were detected by T2 WI,T1WI and SWI were 25,21,47 lesions respectively. The signal of T2 WI and T1 WI were mixed high and low,surrounding by low signal ring or high signal ring,SWI showed low signal. Descending orders of the size of lesion were SWI,T2 WI and T1 WI. SWI showed more small lesions. But no significant differences in SWI,T2 WI and T1 WI measured lesion size( P 0. 05). Conclusion SWI showed cerebral cavernous angioma better than T1 WI and T2 WI imaging. Combined with conventional MRI and SWI can display the cerebral cavernous angioma better and more small lesions.
