Clinical application of susceptibility weighted imaging in cerebral vascular malformation of children

Objective To evaluate the diagnostic value of susceptibility weighted imaging(SWI)in cerebral vascular malformation of children.Methods The imaging data of MRI were retrospectively analyzed in all twenty-seven cases,which included 16 cases of venous angioma,8 cases of cavernous angioma and 3 cases of arterio-venous malformation.The comparison of SWI and conventional MR sequences was obtained.Results The dilated draining veins and medulla veins were displayed well on SWI sequence.More brain cavernous angioma lesions could be detected on SWI than those on conventional MR sequences(P 0.05).Conclusion SWI can detect lesions of venous angioma,cavernous angioma and arterio-venous malformation more sensitively than other sequences,which is a reliable diagnostic technique for cerebral vascular malformation of children.SWI has higher clinical value,and should be the routine sequence in the MRI examination.
