【摘要 】 目的 报告颅外颈动脉CT血管造影(CTA)的初步经验，探讨该技术对各种颅外颈动脉病变的诊断意义，并在可能范围内与数字减影血管造影(DSA)作小样本的对照。 方法 45例颈动脉CTA，经最大密度投影(MaxIP)及表面灰度成像法(SSD)行三维重建，其中5例在1周内作了DSA检查。 结果 45例颈动脉CTA检查，共得到90支血管图像。其中正常血管55支，狭窄血管31支，闭塞血管2支，颈内动脉动脉瘤1支，颈动脉体瘤1支。45例中5例行DSA检查，诊断结果与颈动脉CTA相符。 结论 在本组45例颈动脉CTA检查中，图像质量令人满意，达到诊断要求。此种技术基本成熟，可作为颈动脉分叉处疾病筛选检查的方法。

【Abstract 】 Objective To evaluate spiral computed tomography(CT) angiography in the diagnosis of extracranial carotid artery disease. Methods Forty-five patients referred for evaluation of carotid artery diseases were studied. Beginning with editing the source images three-dimensional MaxIP and SSD images were reconstructed. Of the forty-five patients, five had digital subtraction angiography (DSA) examination within one week time. Results CT angiography of extracranial carotid artery demonstrated 55 normal vessels, 31 stenotic vessels, 2 occluded vessels, 1 internal carotid aneurysm, and 1 carotid body tumor. The diagnosis of the five patients who had DSA examinations correlated well with CT angiography. Conclusions CT angiography can non-invasively provide most of the information about carotid artery disease at its bifurcation.
