摘要
目的研究MR扩散张量成像(DTI)在创伤性轻微脑损伤中的诊断价值。方法选取126例轻微创伤性脑损伤患者及50例骨科无任何脑部疾病史以及脑部创伤患者作为研究对象,分别进行常规CT、MRI及DTI检查,比较两组患者不同部位脑组织(额叶、胼胝体膝部、半卵圆中心、胼胝体压部、顶枕叶、内囊前肢和内囊后肢)各向异性(FA)值。结果对照组额叶、胼胝体膝部、半卵圆中心、胼胝体压部、顶枕叶、内囊前肢和内囊后肢FA值分别为(5.31±0.22)、(8.36±0.22)、(5.88±0.29)、(8.82±0.31)、(5.96±0.17)、(7.90±0.32)、(7.96±0.19);试验组额叶、胼胝体膝部、半卵圆中心、胼胝体压部、顶枕叶、内囊前肢和内囊后肢FA值分别为(3.05±0.30)、(7.05±0.21)、(4.02±0.23)、(7.17±0.26)、(4.22±0.13)、(6.33±0.24)、(6.31±0.10)。试验组患者不同部位脑组织FA值均小于对照组,差异具有统计学意义(P<0.01或P<0.05)。结论 DTI对轻微创伤性脑损伤敏感性较高,能够准确显示白质纤维的损伤情况,诊断效果良好。
Objective To explore the value of MR diffusion tensor imaging （DTI） on diagnosis of mild traumatic brain injury （mTBI） . Methods 126 cases of mBTI patients and 50 cases of bone without any history of brain diseases from our hospital were as the object, CT, MRI and DTI, compared two groups were checked,different parts’ FA values such as cotain the brain, frontal lobe, corpus callosum, the knees, half egg circle center, the ministry of the corpus callosum, occipital lobe, internal capsule forelimbs and internal capsule and hind legs were compared. Results FA value in experimental group was lower than control group（P〈0.01 or P〈0.05）.Conclusion DTI is sensitive for detecting the traumatic injury of white matter, which is helpful for diagnosis earlier and improving prognosis.
