目的:总结性探讨分析颅骨穿透型脑膜瘤的CT和MRI影像学特征,比较其诊断价值。方法:选取21例颅骨穿透型脑膜瘤患者,所有患者都经手术及病理证实,对7例患者采取CT检查,对7例患者采取CT和MRI检查,对7例患者采取MRI检查,比较分析其CT和MRI表现,并和病理分型进行对照。结果:CT和MRI的诊断价值均比较显著。结论:颅骨穿透型脑膜瘤影像学表现都很典型,CT和MRI都有较高诊断价值,MRI的观察效果好于CT检查,CT较MRI有利于观察骨质改变和钙化,MRI能够清晰显示软组织,并对病变范围进行准确判断,在此病的治疗、诊断中可将二者结合使用。
Objective: To summarize and analyze the CT and MRI features of skull penetrating meningioma and to compare the diagnostic value. Methods: Twenty-one patients with penetrating meningioma of skull were selected. All the patients were proved by operation and pathology. CT was performed on 7 patients, CT and MRI were performed on 7 patients, MRI was performed on 7 patients, and comparative analysis was performed The CT and MRI performance, and pathological typing were compared. Results: The diagnostic value of CT and MRI were significant. CONCLUSION: The imaging features of CTT are typical. Both CT and MRI have high diagnostic value. MRI is better than CT. CT is better than MRI in observing bone changes and calcifications. MRI can clearly show Soft tissue, and accurately determine the extent of the lesion in the treatment of the disease, the diagnosis can be used in combination.
