【摘要】 目的比较脑膜瘤的ＣＴ、ＭＲＩ、ＤＳＡ的诊断价值。材料与方法６４例脑膜瘤全部行ＣＴ、ＭＲＩ检查，其中３０例行ＤＳＡ检查。结果ＣＴ对脑膜瘤的诊断具有较高的密度敏感性，能够直观地显示钙化及邻近骨质的变化；ＭＲＩ对脑膜瘤诊断信号敏感性稍差，但通过多维扫描可提高脑膜瘤的检出率；ＤＳＡ能够清楚地显示肿瘤的血供特点，颈外动脉供应肿瘤的中心部分，颈内动脉供应肿瘤的周边部分。结论ＣＴ和ＭＲＩ相结合可提高对脑膜瘤诊断的符合率，ＤＳＡ为进一步手术治疗提供明确的血管解剖定位。更多还原

【Abstract】 Purposes To compare the CT,MPI,DSA diagnostic value of meningioma’ Materials and methods 64 patients with meningioma were studied by CT and MRI, 30 patients with meningioma were studied by DSA. Results It is more susceptive for CT to diagnoses meningioma CT can shaw directly calcification and change of adjacent bone. It is less susceptive for MRI to diagnoses meningioma, but MRI can improve the diagnosis rate of meningioma through multi - dimensional scaning’ DSA can show the angiogra phy in meningioma. External carotid artery Supply the central part of meningioma, niternal carotid artery supply the other part of meningioma. Conclusion Combining CT into MRI will improve diagnosis rate. DSA show accurate angio - anatomy for next surgical curing更多还原
