Abstract:
Objective To assess the clinical application value of magnetic susceptibility-weighted imaging in cerebral vascular malformations. Methods Thirty-six patients with cerebral vascular malformations were enrolled in the study. All the patients received examination of T1WI, T2WI and SWI. SWI sequence was compared with T1WI, T2WI sequence in detecting and diagnosing cerebral vascular malformations. Results Cerebral vascular malformations were low signal in SWI sequence. Cavernous angioma, developmental venous anomalies and AVM had been found in 73,8,10 cases, respectively. The bounder of lesions was clearer, more multiple small lesions, more hair-thin pulp veins and draining veins were detected in SWI sequence. Conclusion SWI sequence has more sensitivity than T1WI and T2WI sequence in detecting the cerebral-vascular malformations. SWI sequence may become routine examination se- quence in diagnosis cerebral-vascular malformations.
