摘　　要：目的评价64层螺旋CT诊断颅内动脉瘤的临床应用价值。方法选取我院176例颅内动脉瘤患者的头颈CTA(computed tomographic angiography,CTA)检查资料,评价颅内动脉瘤的大小、形态、位置及术后情况。结果 176例均行数字减影血管造影(digital subtraction angiography,DSA)存在动脉瘤(157经手术治疗),共计201个动脉瘤,其中19例为多发动脉瘤。首次CTA明确诊断动脉瘤171例(196个),漏诊5例,阳性诊断率97.5%(196/201)。171例(196个)中颈内动脉瘤112例,后交通动脉瘤10例,前交通动脉瘤26例,基底动脉瘤5例,大脑中动脉瘤13例,大脑前动脉瘤5例,对照DSA再次重组首次漏诊的5例CTA图像,又发现动脉瘤2例,阳性诊断率提高至98.5%。结论应用多层螺旋CT头颈血管联合成像选择合理的后处理方法,有助于提高图像质量与诊断的准确性,对临床术前评估与术后评价有重要意义。Objective To evaluate the diagnostic value of 64 multidetector-row CT head and neck angiography for intracranial aneurysm. Methods 176 intracranial aneurysm patients were recruited, and evaluated for size, shape, position of the aneurysms by 64 multidetector-row CT head and neck angiography. Results 176 patients were examined by DSA, including 157 post-operative patients. 201 aneurysms were detected, including 19 multiple aneurysms. Of the total, 171 patients were first identified（196 aneurysms）, 5 patients missed diagnosis, and the rate of positive diagnosis was 97.5%（196/201）. Of the 171 patients, 112 had internal carotid aneurysms, 10 had posterior communicating aneurysms, 26 anterior communicating aneurysms, 5 basilar artery aneurysm, 13 middle cerebral artery aneurysm, 5 anterior cerebral artery aneurysms. Another 2 patients with aneurysms were identified after re-examination. Conclusions The application and rational post-processing of 64 multidetector-row CT head and neck angiography were of significant importance for preoperative postoperative evaluation of intracranial aneurysms.
