Abstract：Objective: To evaluate the diagnostic value of susceptibility weighted imaging (SWI) in cerebral vascular malformations of children. Methods: Thirty eight cases of cerebral vascular malformations of children underwent routine magnetic resonance imaging (MRI) and SWI examination, which included 11 cases of arterio-venous malformations (AVM), 8 cases of cerebral venous malformations (CVM), 14 cases of cavernous hemangiomas (9 cases of solitary and 5 cases of multiple) and 5 cases of intracerebral capillary telangiectasia (ICT). Seven cases performed routine gadopentetate dimeglumine (Gd-DTPA) enhanced MRI scan. The difference of SWI and conventional MRI sequences on detection of cerebral vascular malformations was compared. Results: Thirty eight cases of cerebral vascular malformations were well-displayed on SWI. The detection rate of conventional MRI in AVM, cavernous hemangiomas, CVM and ICT were 100.0%, 78.6%, 37.5% and 20.0% respectively. While the detection rate of SWI in them were all 100.0%. SWI was obviously superior to conventional MRI on demonstrating microbleed foci, draining veins and medullary veins of cerebral vascular malformations. Conclusion: Comparing with conventional MRI, SWI can clearly show more details and detect more small lesions of cerebral vascular malformations, and avoid the missed diagnosis. It has an important value for the diagnosis and differentiation diagnosis of cerebral vascular malformation in children.
