慢性硬膜下血肿的CT与MRI对比研究

目的：对比研究慢性硬膜下血肿的CT与MRI诊断效果。方法：回顾性分析本院收治的40例慢性硬膜下血肿患者资料，其中25例行CT检查，15例行MRI检查，观察两种检查方法的影像学表现及误诊情况。结果：CT检查法的误诊率为24.00%（6/24），显著高于MRI的0（P〈0.05）；CT检查发现，中等密度、高密度、低密度及混合密度血肿患者例数分别为：6例、4例、6例与9例，其中共有5例等密度血肿患者CT增强显示不清；MRI检查15例患者均能正确诊断。结论：按照科学精准的CT与MRI检查步骤对慢性硬膜下血肿患者进行检查，对疾病的正确诊断两者均具有重要的参考意义，但MRI的误诊率更低，对于中等密度血肿患者，宜采用MRI检查，值得临床上进行推广研究与应用。

Chronic Subdural Hematoma Comparative Study of CT and MRI

Objective： To study the diagnosis results of chronic subdural hematoma （CSH） CT and MRI. Method： To retrospectively analyze 40 CSH patients, 25 cases did routine CT, 15 cases did MRI,compare misdiagnosis and imaging findings of two methods.Result： CT examination method’s misdiagnosis rate was 24.00%（6/24）, significantly higher than MRI （0） （P〈0.05）; CT examination found that medium-density, high-density, low density, and mixed density hematoma cases, respectively were： 6 cases, 4 cases, 6 cases and 9 cases, in which a total of 5 cases of equal density hematoma, enhancement CT showed unclear. After MRI examination, 15 patients could be correct diagnosis.Conclusion： Based on scientific precision CT and MRI examination procedure for patients with CSH to check the correct diagnosis of the disease both have important reference value, but the MRI misdiagnosis rate is lower, for medium-density hematoma patients, should adopt MRI examination, it is worth to promote clinical research and application.
