Abstract：【Objective】To investigate the applicable value of susceptibility weighted imaging(SWI) in diagnosis of intracranial cavernous angioma(ICA) in children. 【Methods】 The clinical data of 23 children with ICA confirmed by operation were retrospectively analyzed, and the conventional MRI sequences and SWI sequences of the skull were scanned and examined. Among them, 14 cases were male and 9 were female. The size, shape and signal characteristics of the lesions were compared and analyzed. The advantages of SWI sequence in the diagnosis of ICA in children were comprehensively evaluated.【Results】All ICA lesions were displayed in SWI sequence, and had the typical characteristics of the "hoop sign, mulberry, popcorn syndrome". With round or about round shape, and irregular shape with very low signal and mixed signal, the boundary was clear, the focus diameter was about 0.20 ~ 5.71 cm. Conventional MRI sequence scan can not show the lesions of less than 3 mm, However, the SWI sequence is mainly based on the class of low signal and mixed signal, more sensitive to the detection of trace and still bleeding, and the display of small vein blood vessels is more clear.【Conclusion】 SWI sequence scanning in children with ICA has a high sensitivity to make up for the lesions that the routine MRI sequence scan fails to find, and has important value for the early diagnosis of ICA in children.
