MSCTA在颅内动脉瘤诊断中的应用

The Application of Multi-Slice CT Angiography in Diagnosis of Intracranial Aneurysm

    摘要
  • 摘要: 目的: 探讨多层螺旋CT血管成像在颅内动脉瘤的诊断中的应用。方法: 收集经手术证实或DSA的颅内动脉瘤31例,所有的病例均行多层螺旋CT血管成像。CTA通过采取VR、MIP及CPR等后处理重建技术,实现脑内血管重现,展现颅内血管的真实情况。20例行手术治疗,11例行DSA检查。结果: 本组31例,共36个颅内动脉瘤。29例单发,2例多发(7个动脉瘤)。MSCTA发现颅内动脉瘤33个,1个动脉瘤误诊;MSCTA正确诊断动脉瘤32个,4个动脉瘤漏诊。MSCTA诊断颅内动脉瘤的准确率为97%(32/33),敏感度为89%(32/36),平均直径为8mm(范围在3~35mm之间)。MSCTA所显示的动脉瘤与手术及DSA所见显示动脉瘤位置、大小、形态基本一致。结论: MSCTA能清楚显示颅内动脉瘤的形态、位置及其与周围的解剖关系,其诊断结果与DSA或/手术诊断符合率相当高,在颅内动脉瘤的诊断中有重要的价值。

     

    Abstract: Objective: To evaluate the application values of multislice CT angiography(MSCTA)in the diagnosis of cerebral aneurysms.Materials and Methods MSCTA were performed in 31 patients with cerebral aneurysms confirmed by DSA or operation.CTA were processed with maximum intensity projection(MIP),volume rendering(VR)and curved planar reformation(CPR).20 patients were performed operation and 11 patients were performed operation.Results: 36 cerebral aneurysms were found in 31 patients.29 cases were solitary and 2 cases were multiple(5 cerebral aneurysms).33 cerebral aneurysms were found in MSCTA,but 1 was misdiagnosed.32 cerebral aneurysms were diagnosed correctly by MSCTA,and 4 were missed on the MSCTA.The accurate rate was 97%(32/33)and sensitivity was 89%(32/36).The diameter were between 3~35 mm with average size of 8mm on MSCTA images.The location,size and appearance of cerebral aneurysms showed in MSCTA images were in accordant with the result of DSA and operations.Conclusion: MSCTA can display clearly the location,size and appearance of cerebral aneurysms accurately and objectively.MSCTA and DSA or surgery have high diagnose accordance rate.It plays an important role in the diagnosis of the disease.
