摘要 目的:分析和评价小儿头颈部血管瘤和静脉畸形的磁共振扩散加权成像(MR-DWI)特点。方法:对10例小儿头颈部血管瘤和40例静脉畸形患者进行回顾性分析,在MR-DWI图像上分别取b值为500s/mm2和1000s/mm2,获取其表观弥散系数(ADC)均值,应用SPSS13.0软件包进行t检验。结果:b值为500s/mm2时,血管瘤ADC值为(1.227±0.324)×10-3mm2/s,静脉畸形ADC值为(1.851±0.364)×10-3mm2/s;b值为1000s/mm2时,血管瘤ADC值为(0.728±0.256)×10-3mm2/s,静脉畸形ADC值为(1.200±0.228)×10-3mm2/s。经配对t检验,两者之间有显著性差异(P<0.01)。结论:小儿头颈部血管瘤和静脉畸形的MR-DWI特点各不相同,影像学检查有助于鉴别诊断。 PURPOSE： To analyze and evaluate the MR diffusion-weighted imaging（MR-DWI） features of head and neck hemangioma and venous malformation in children.METHODS： We retrospectively observed 10 head and neck hemangiomas and 40 head and neck venous malformations in children,which underwent both conventional MR imaging and MR-DWI.In the MR-DW images,the apparent diffusion coefficient（ADC） mean value was taken from b=500s/mm^2 and 1000 s/mm^2,The data was analyzed using SPSS13.0 software package for t test.RESULTS： The mean ADC obtained from b value of 500 s/mm^2 was（1.227 ±0.324） ×10^-3mm^2/s in hemangioma and（1.851 ±0.364） ×10^-3mm^2/s in venous malformation,and from b value of 1000 s/mm^2 was（0.728±0.256）×10^-3mm^2/s in hemangioma and（1.200±0.228）×10^-3mm^2/s in vein malformation.There was significant difference between both lesions（P0.01）.CONCLUSION： There are different features in MR-DWI between head and neck hemangioma and venous malformation in children,which may be helpful for radiological differential diagnosis.
