【摘要】目的 探讨64排螺旋CT血管成像(64 SCTA)在头颈部动脉瘤诊断中的临床应用.方法 回顾性分析经手术或DSA证实为头颈部动脉瘤的患者75例,所有病例均行64 SCTA检查,对其图像资料进行分析,并与手术或DSA检查结果作比较,以评价64 SCTA在头颈部动脉瘤诊断中的准确性.结果 75例患者共82个动脉瘤,其中颈内动脉5个、基底动脉8个、前交通动脉18个、后交通动脉11个、大脑前动脉15个、大脑中动脉12个、大脑后动脉13个.以手术或DSA检查结果作为标准,64 SCTA 准确诊断78个动脉瘤,漏诊2个,2个为假阳性.64 SCTA能够非常清晰地显示头颈部动脉瘤的具体形态、位置、瘤体大小、瘤颈、载瘤动脉及动脉瘤与周围组织结构的解剖关系,其诊断头颈部动脉瘤的敏感性和准确性分别为97.5%和95.1%.结论 64 SCTA在头颈部动脉瘤的诊断中具有较高的准确性,它作为一项无创、快速、准确的检查手段,可作为术前常规及首选的检查方法.%Objective To investigate the clinical application of 64-slicc spiral CT angiography (64-SCT A) in the diagnosis of the head and neck ancurysms. Methods The image data of 64-SCTA of 75 patients of the head and neck ancurysms proved by operation or DSA were analyzed retrospectively. The diagnostic accuracy of 64-SCTA in the head and neck ancurysms were evaluated by operation or DSA examination results as gold standard. Results There were 82 ancurysms in the 75
