【摘要】：目的通过磁共振扩散加权影像技术来研究正常健康人群的腰椎各部分的表观弥散系数之间的差异以及与年龄的相关性,为提高成人腰椎病变检查的准确性及可靠性。方法选取2015年07月至2016年08月期间来我院进行正常体检的人员,经筛选最终选择60例,其中男性为28例,女性为32例,平均年龄为(53.26±18.13)岁,分为中年、老年、青年三个年龄段组,进行腰椎正中矢状切面T2弛豫时间图像扫描,用以量化并分析腰椎内水分子的含量,同时进行腰椎正中矢状切面扩散加权影像扫描,用以分析腰椎内水分子的扩散程度,将获得的数据进行统计分析,分析不同年龄段组之间的腰椎各部分ADC值的差异。结果正常健康成人的腰椎不同部位的ADC值存在显著性差异(P0.05),椎弓根的ADC值大于椎体;腰椎各部位的ADC值随年龄段的变化呈现显著性差异(P0.05),青年组的ADC值大于中年组和老年组,老年组的ADC值最小。结论在以后研究腰椎病变时,一定要对照同样年龄段的正常健康人群来判定,这样才能提高诊断的效率和准确度。
[Abstract]:Objective to study the difference of apparent diffusion coefficient between different parts of lumbar vertebrae and its correlation with age by using diffusion weighted imaging (DWI) in normal subjects, in order to improve the accuracy and reliability of lumbar vertebrae disease examination in adults.Methods from July 2015 to August 2016, 60 healthy persons were selected, including 28 males and 32 females, with an average age of 53.26 卤18.13 years. They were divided into three age groups: middle age, old age and youth.In order to quantify and analyze the content of water molecules in lumbar vertebrae, the median sagittal section of lumbar vertebrae was scanned with T2 relaxation time image to analyze the diffusion degree of water molecules in lumbar vertebrae, and at the same time, the diffusion weighted image of median sagittal section of lumbar vertebrae was performed.The data obtained were statistically analyzed to analyze the differences of ADC values between different age groups.Results there were significant differences in ADC values in different parts of lumbar vertebrae in healthy adults (P 0.05), the ADC value of pedicle was larger than that of vertebrae, the ADC value of lumbar vertebrae showed significant difference with age. The ADC value of young group was higher than that of middle age group and old group.The ADC value of the elderly group was the lowest.Conclusion in order to improve the efficiency and accuracy of diagnosis, it is necessary to compare the normal population of the same age in the later study of lumbar spondylopathy.
