Abstract

Objective:To discuss the value of susceptibility weighted imaging (SWI) in the brain vascular malforma- tions.Methods:From March 2008 to July 2008,6 patients with brain vascular malformations,including 5 cases of cavern- ous angioma,1 case of venous malformation,were examined with a 1.5 TMR scanner.The images of SWI were reconstruc- ted by minimum intensity projection in 10 mm thickness.The comparison of SWI and conventional MR sequences was ob- tained.Results:SWI showed all the cases clearly.In 5 cases of patients with cavernous angioma,9 lesions were shown by SWI,only 5 shown by conventional sequence.Conclusion:SWI should be used in combination with other sequence,as a routine MR sequence for detecting brain vascular malformation and providing more complete and detailed information.
