【摘要】：目的通過磁共振擴散加權(quán)影像技術(shù)來研究正常健康人群的腰椎各部分的表觀彌散系數(shù)之間的差異以及與年齡的相關(guān)性,為提高成人腰椎病變檢查的準(zhǔn)確性及可靠性。方法選取2015年07月至2016年08月期間來我院進(jìn)行正常體檢的人員,經(jīng)篩選最終選擇60例,其中男性為28例,女性為32例,平均年齡為(53.26±18.13)歲,分為中年、老年、青年三個年齡段組,進(jìn)行腰椎正中矢狀切面T2弛豫時間圖像掃描,用以量化并分析腰椎內(nèi)水分子的含量,同時進(jìn)行腰椎正中矢狀切面擴散加權(quán)影像掃描,用以分析腰椎內(nèi)水分子的擴散程度,將獲得的數(shù)據(jù)進(jìn)行統(tǒng)計分析,分析不同年齡段組之間的腰椎各部分ADC值的差異。結(jié)果正常健康成人的腰椎不同部位的ADC值存在顯著性差異(P0.05),椎弓根的ADC值大于椎體;腰椎各部位的ADC值隨年齡段的變化呈現(xiàn)顯著性差異(P0.05),青年組的ADC值大于中年組和老年組,老年組的ADC值最小。結(jié)論在以后研究腰椎病變時,一定要對照同樣年齡段的正常健康人群來判定,這樣才能提高診斷的效率和準(zhǔn)確度。
[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 鹵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.
