摘要
目的探讨64排CT双期血管造影技术在脑膜瘤术前评估中的作用。方法回顾性分析40例病理证实的脑膜瘤术前影像资料,与手术结果对照,评估CT双期血管造影显示脑膜瘤与周围脑血管及颅骨关系的准确性。结果 40例脑膜瘤中,肿瘤未累及血管者21例,侵蚀动脉者10例,侵犯静脉窦者9例,侵犯颅骨者12例,其术中吻合度分别为90.5%、88.9%、100%和91.7%。结论 CT双期血管造影可准确显示肿瘤与动脉、静脉窦及颅骨的关系,在脑膜瘤术前评估中有非常重要价值。
Objective To assess the diagnostic value 64-detector helical CT dural-phase angiography in the preoperative evaluation of meningiomas.Methods The imaging data were retrospectively examined in 40 patients with meningioma confirmed pathologically,and were compared with the operative findings in order to evaluate the accuracy of dual-phase CT scanning results of the peripheral cerebral ves-sels in angiography and the tumor involvement of the skull structure.Results Of the 40 cases,tumor involvement of the peripheral cerebral vessels was free in 27,involvement of the artery was in 10,of sinus venosus in 9 and skull in 12.Operative findings were identical to the previ-ous CT results by 90.5%,88.9%,100% and 91.7%,respectively.Conclusion Dual-phase CT angiography can clearly define the tumor boundary between the tumor and artery,vessels,sinus venosus and skull,and is thus of diagnostic significance in the preoperative evaluation of meningiomas.
