摘　　要：目的比较CT和MRI在小脑膜瘤诊断中的应用价值。方法回顾性分析48例小脑膜瘤患者的CT和MRI资料,比较不同检查方法的诊断敏感性。结果 CT、MRI平扫、MRI增强诊断小脑膜瘤的灵敏度分别为77.08%、83.33%、97.92%,MRI增强的灵敏度高于CT和MRI平扫(χ2分别=9.52、4.37,P均<0.05),而MRI平扫的灵敏度与CT比较,差异无统计学意义(χ2=0.59,P>0.05)。结论 CT和MRI均能较好地诊断小脑膜瘤,而MRI增强扫描对小脑膜瘤的诊断敏感性更高,有利于早期明确小脑膜瘤的诊断。Objective To compare the diagnostic value of CT and MRI on small menigioma. Methods The CT and MRI data of 48 cases of patients suffered from small menigioma were analyzed retrospectively, the diagnostic sensitivities were compared. Results The sensitivity of CT, non-contrast MRI and contrast enhanced MRI were 77.08%, 83.33% and 97.92%respectively. The sensitivity of contrast enhanced MRI were significantly higher than CT and non-contrast MRI（χ2=9.52, 4.37, P〈0.05）. There was no statistical difference between non-contrast MRI and CT （χ2=0.59,P〉0.05）. Conclu-sion Both CT and MRI could diagnose small menigioma effectively, while the sensitivity of the contrast enhanced MRI is higher which is benefit for early diagnosis of small menigioma.
