摘　　要：目的探寻复杂型儿童热性惊厥急性发作时双侧海马组织的弥散特点。方法收集2017年8月至2018年2月期间急性期复杂型热性惊厥患儿20例作为研究实验组,同年龄段非中枢系统疾病儿童20例为对照组,进行两组双侧海马多b值(0~1000s/mm;)DWI扫描,ADC图重建及ADC值测量。最后用SPSS 17.0统计软件包进行统计分析。结果在b值等于1000s/mm;时,左侧海马实验组与对照组之间ADC值有统计学差异(t=2.690,P=0.01),右侧海马实验组与对照组ADC值有统计学差异(t=3.02,P=0.005)。结论当b值等1000s/mm2时,相应ADC值可以敏感捕捉到急性复杂型儿童热性惊厥海马损伤证据,具有一定临床应用价值。Objective Exploring the diffuse characteristics of bilateral hippocampus in acute complex febrile seizures of children.Methods Twenty children with acute complex febrile seizures were enrolled as the experimental group,and 20 children with non-central system diseases of the same age group were used as the control group between August 2017 and February 2018.Multi-b value(0~1000 s/mm;)DWI scan,ADC map were rebuilt,and ADC value were measured.Finally SPSS 17.0 statistical software package was used to conduct statistical analysis.Results When the b value was equal to 1000 s/mm;,the ADC value between the left hippocampal experimental group and control group was statistically different(t=2.690,P=0.01),and the ADC value between the right hippocampal experimental group and control group was statistically different(t=3.02,P=0.005).Conclusion When the b value is equal to 1000 s/mm;,the corresponding ADC value can be sensitive to capture evidence of hippocampus damage in acute complex febrile seizures,has certain clinical application value.
