目的:对比外伤性视神经病采用螺旋CT与MRI诊断的价值。材料与方法:资料选取本院2013年9月-2015年9月收治的外伤性视神经病100例患者进行回顾性分析,按照诊断时所用方法分为螺旋CT组与MRI诊断组,观察并比较两组具体诊断价值。结果:经MRI检查发现视神经损伤2例移位,12例鞘膜下出血,38例萎缩,46例水肿;经螺旋CT检查发现视神经管的骨折部位存在6例蝶鞍型,20例管前型,26例半管型,38例全管型,两组和病理学结果相比均无统计学意义(P>0.05)。结论:外伤性视神经病患者采用螺旋CT与MRI诊断价值高,利于疾病检出率提高,且MRI技术能够对视神经具体损伤情况予以准确判断,螺旋CT技术能够清晰将视神经具体骨折部位显现,将螺旋CT与MRI诊断结合,能够为临床制定合理治疗计划提供更为充分的依据,可应用于临床。
Objective: To compare the value of spiral CT and MRI in the diagnosis of traumatic optic neuropathy. Materials and Methods: The data were retrospectively analyzed in 100 patients with traumatic optic neuropathy from September 2013 to September 2015 in our hospital. According to the methods used in diagnosis, spiral CT and MRI were divided into two groups. Group specific diagnostic value. Results: Two cases of optic nerve injury, 12 cases of subdural hemorrhage, 38 cases of atrophy and 46 cases of edema were found by MRI examination. There were 6 cases of optic chiasma in 20 cases , 26 cases of semi-tubular and 38 cases of total tubular. There was no significant difference between the two groups (P> 0.05). CONCLUSIONS: CT and MRI are of great value in the diagnosis of traumatic optic neuropathy, which is beneficial to improve the detection rate of the disease. MRI can accurately judge the specific damage of the optic nerve. Spiral CT can clearly show the specific fracture site of optic nerve, The combination of CT and MRI diagnosis can provide a more sufficient basis for making a reasonable clinical plan for clinical application.
