摘　　要：目的研究分析创伤性颅脑损伤临床诊断与预后评估中运用磁共振扩散张量成像的临床效果。方法选择2023年7月1日至2023年12月31日期间医院收治的创伤性颅脑损伤患者30例为研究对象,再选择同期来医院体检的35例健康者为对照组,均行常规MRI检查、DTI成像以及CT检查,分别测量计算并记录FA值,并且对两组不同部位的FA值进行比较分析。结果观察组的EC、AIC、PIC、SC、GCC以及SCC分别为(0.551±0.065)、(0.609±0.045)、(0.585±0.059)、(0.536±0.046)、(0.601±0.053)、(0.531±0.049),均低于对照组的(0.769±0.055)、(0.719±0.097)、(0.829±0.065)、(0.759±0.053)、(0.784±0.051)、(0.743±0.047),组间比较差异有统计学意义(P<0.05);根据GCS评分,观察组的30例患者中,4例为重度、16例为中度、10例为轻度;但是观察组左侧与右侧SCC、GCC、SC、PIC、AIC以及EC的FA值对比差异无统计学意义(P>0.05);同时,经相关性分析,发现观察组的FA值与GCS呈正比关系,并且DTI异常与患者脑伤后遗症对比差异有统计学意义(P<0.05)。结论创伤性颅脑损伤患者的病情严重程度与FA值变化密切相关,通过运用磁共振弥扩散张量成像技术,能够提高疾病的早期诊断准确率,可以准确评估患者病情,为制定针对性治疗方案和判断预后提供一定的参考依据。Objective To study and analyze the clinical effect of using magnetic resonance diffusion tensor imaging in the clinical diagnosis and prognosis evaluation of traumatic craniocerebral injury.Methods Thirty patients with traumatic craniocerebral injury admitted to the hospital from July 1,2023 to December 31,2023 were selected as the study subjects,and 35 healthy subjects who came to the hospital for physical examination during the same period were selected as the control group.Routine MRI examination,DTI imaging and CT examination were performed,and FA values were measured,calculated and recorded,respectively.The FA values of different parts of two groups were compared and analyzed.Results In the observation group,EC,AIC,PIC,SC,GCC and SCC were(0.551±0.065),(0.609±0.045),(0.585±0.059),(0.536±0.046),(0.601±0.053)and(0.531±0.049),respectively.They were lower than those in the control group(0.769±0.055),(0.719±0.097),(0.829±0.065),(0.759±0.053),(0.784±0.051),(0.743±0.047),and the difference between groups was statistically significant(P<0.05).According to GCS scores,among the 30 patients in the observation group,4 cases were severe,16 cases were moderate,and 10 cases were mild.However,there was no significant difference in FA values of SCC,GCC,SC,PIC,AIC and EC between the left and right sides of the observation group(P>0.05).Meanwhile,through correlation analysis,it was found that the FA value in the observation group was positively correlated with GCS,and the difference between abnormal DTI and sequelae of brain injury was statistically significant(P<0.05).Conclusion The severity of traumatic brain injury patients is closely related to the change of FA value.The application of magnetic resonance diffusion tensor imaging technology can improve the accuracy of early diagnosis of the disease,and can accurately evaluate the patient's condition,providing a certain reference for making targeted treatment plans and judging the prognosis.
