In order to assess the value of magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) in microscopic brain scans. Diffusion tensor imaging (DTI) and magnetic resonance spectroscopy (MRI) changes over time in patients with traumatic brain injury (TBI) show a relationship between recovery from coma and overall Glasgow prognostic parameters. The value of DTI combined with MRI in evaluating TBI has been investigated. 10 patients with TBI received 10 evaluations of magnetic resonance imaging, DTI and MRI scans. Thalamic plate nucleus, reticular nucleus, and retinal developmental activity were measured in normal controls and TBI coma (2-3 weeks) and mild (>4 weeks) patients. Anisotropy, mean diffusion coefficient, axial diffusion coefficient, and radial diffusion coefficient were measured using MRI together with acetylaspartic acid, choline, creatinine, and lactic acid. Independent control -tests were conducted between controls and TBI patients, and 1-test paired between moderate and severe injuries, and regression and correlation were evaluated. Evaluated for all measures and treatments. DTI and MRI scores in TBI patients differed from normal controls. DTI and MRI can predict the prognosis of TBI patients better. The limitations of the thalamus-retinal activation system are gradually restored. axial diffusion coefficient and radial diffusion coefficient can be used to evaluate the reliability of comatose patients with TBI. DTI and MRI scans of the patient's brain can predict recovery and guide treatment in TBI coma patients.
为了评估磁共振成像（MRI）和弥散张量成像（DTI）在微观脑扫描中的价值。弥散张量成像（DTI）和磁共振波谱（MRI）在创伤性脑损伤（TBI）患者中的变化与昏迷恢复和整体格拉斯哥预后参数之间存在关系。DTI 与 MRI 联合评估 TBI 的价值已被研究。10 例 TBI 患者接受了 10 次 MRI、DTI 和 MRI 扫描评估。在正常对照组和 TBI 昏迷（2-3 周）和轻度（>4 周）患者中测量丘脑板核、网状核和视网膜发育活性。使用 MRI 测量各向异性、平均扩散系数、轴向扩散系数和径向扩散系数，并测量乙酰天门冬氨酸、胆碱、肌酸和乳酸。在正常对照组和 TBI 患者之间进行独立的对照测试，在中度和重度损伤之间进行配对测试，并评估回归和相关性。对所有措施和治疗进行评估。TBI 患者的 DTI 和 MRI 评分与正常对照组不同。DTI 和 MRI 可以更好地预测 TBI 患者的预后。丘脑-视网膜激活系统的局限性逐渐恢复。轴向扩散系数和径向扩散系数可用于评估昏迷 TBI 患者的可靠性。患者大脑的 DTI 和 MRI 扫描可以预测 TBI 昏迷患者的恢复并指导治疗。
