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-slice spiral CT angiography （64 S（？TA） in the diagnosis of thehead and neck aneurysms. Methods The image data of 64-SCTA of 75 patients of the head and neck aneurysms proved by operation or DSA were analyzed retrospectively. The diagnostic accuracy of 64-SCTA in the head and neck aneurysms were evaluated by opera- tion or DSA examination results as gold standard. Results There were 82 aneurysms in the 75 patients. Among them, 5 aneurysms located internal carotid artery , 8 in basilar artery, 18 in anterior communicating artery, 11 in posterior communicating artery, 15 in anterior cerebral artery , 12 in middle cerebral artery and 13 in posterior cerebral artery. Compared with the results of operation or DSA, 78 aneurysms were exactly diagnosed by 64-SCTA in these 75 patients. 2 false positive and 2 false negative cases were identi- fied by 64-SCTA. 64-SCTA showed the aneurysms＇ form, location, size and neck clearly, as well as the relationship with the adja- cent structures. The sensitivity and accuracy were 97.5% and 95%. Conclusion 64-SCTA presents high accuracy in the diagnosis of the head and neck aneurysms. As a fast, non-invasive and accurate examination, it can be used as an optimal and routine method inthe head and neck aneurysms diagnosis.
