摘　　要：目的 探讨双源CT血管成像（CTA）在肠系膜上动脉狭窄诊断中的价值.方法 对11例经数字减影血管造影（DSA）证实的肠系膜上动脉狭窄患者的双源CTA图像进行分析.以DSA为金标准,统计双源CTA诊断肠系膜上动脉不同程度狭窄的敏感度、特异度.结果 双源CTA诊断肠系膜上动脉轻度、中度、重度狭窄及闭塞的敏感度分别为86%、82%、100%,特异度分别为96%、92%、96%.结论 双源CTA能快速、准确地诊断肠系膜上动脉狭窄.Objective To evaluate the value of dual-source CT angiography（CTA） in diagnosis of superior mesenteric artery （SMA） stenosis. Methods CTAof 11 patients with superior mesenteric artery stenosis confirmed by digital subtractionangiography （DSA） were analysed. With the results of DSA as gold standard,the sensitivity and specificity of CTA in diagnosis of superior mesenteric artery stenosis were also evaluated. Results The sensitivity and specificity for diagnosing stenosis of superior mesenteric artery in different degree（mild,moderate and severe） were 86%,82% and 100%,96%,92% and 96% ,respectively. Conclusion Tbe dual-source CTA can diagnose the superior mesenteric artrery stenosis quickly and accurately.
