Abstract：Objective:To compare the value of magnetic susceptibility weighted imaging (SWI) sequence imaging and conventional MRI sequence in the diagnosis of cerebral cavernous malformation (CCM). Methods:The clinical data of 75 patients with intracranial CCM confirmed by operation who were admitted to the hospital from September 2013 to August 2017 were retrospectively analyzed. All patients underwent brain MRI conventional sequence and SWI sequence scan, and the imaging data were complete and clear. The effects of SWI sequence and MRI conventional sequence (T1WI, T2WI) in displaying cerebral vascular lesions were analyzed. Results: There were 115 lesions in 75 patients with intracranial CCM, including 97 supratentorial lesions and 18 subtentorial lesions. Lesions detected by SWI sequence were the most (115), more than those detected by T1WI sequence or T2WI sequence (93 and 101 respectively). The maximum diameter of supratentorial lesions displayed by SWI sequence was significantly longer than that by T1WI sequence or T2WI sequence (P<0.05), but there was no significant difference in the maximum diameter of subtentorial lesions (P > 0.05). Conventional MRI sequences showed low signal rings around CCM lesions, showing T1WI high signal, T2WI high or mixed signal, and enhanced scan sequence did not show significant enhancement. The extent of lesion displayed by SWI was larger than that by conventional T1WI or T2WI sequence. It could clearly showed single or multiple patchy low signal with venous malformation and bleeding, and CCM which were difficult to be displayed by conventional MRI sequence showed small nodular low signal on SWI. Conclusion: SWI sequence imaging is superior to conventional MRI sequences in displaying the range, quantity and small lesions of CCM. It is of great value in the qualitative and quantitative diagnosis of CCM.
