| 目的 探讨MSCTA对急性肠系膜上动脉(SMA)栓塞的诊断价值。 方法 选用6只杂种犬建立犬急性SMA栓塞模型。分别于栓塞前及栓塞后行DSA、MSCTA检查。对原始CT图像采用MIP及VR技术进行重建。以DSA为金标准,计算并比较MIP、VR两种后处理技术诊断急性SMA栓塞的敏感度和特异度。 结果 6只犬均成功建立急性SMA栓塞模型。MSCTA图像均能清晰显示肠系膜上动脉主干至二级分支。采用MIP技术的诊断敏感度为96.40%,特异度为90.50%,VR技术的诊断敏感度为92.85%,特异度为90.50%。两种后处理技术诊断SMA栓塞的特异度、敏感度差异无统计学意义。 结论 MSCTA简便易行,能准确诊断犬急性SMA栓塞。 |

| Objective To observe the diagnostic value of MSCTA in acute superior mesenteric artery (SMA) embolization of canines. Methods Six mongrel dogs were selected to establish the models of acute superior mesenteric artery embolization. DSA and MSCTA were performed before and after embolization. MSCT images were reconstructed using MIP and VRT. Taking findings of DSA as gold standard, the sensitivity and specificity of MIP and VRT were calculated and compared. Results The models of acute superior mesenteric artery embolization were successfully established in all 6 canines. Both SMA and grade 2 branches were displayed clearly. The sensitivity of MIP and VRT was 96.40% and 92.85%, respectively, and the specificities were both 90.50%. No statistical difference was found between MIP and VRT. Conclusion MSCTA is simple and accurate, able to be used for diagnosing acute superior mesenteric arterial embolization. |
