[摘要] 目的 分析結肠癌MSCT动态增强扫描联合后处理技术的诊断价值。 方法 回顾性选取2018年2月至2019年11月九江市第一人民医院医学影像科结肠癌患者82例，全部患者均接受多层螺旋电子计算机断层扫描（MSCT）动态增强扫描，并将获取的图像均经后技术处理。观察诊断结果，将手术病理检查结果作为金标准，分析MSCT动态增强扫描联合后处理技术对结肠癌患者的诊断效能。 结果 82例患者中，手术病理检查阳性62例，阴性20例;MSCT动态增强扫描单独检查阳性54例，阴性28例。与手术病理检查结果比较，MSCT动态增强扫描单独检查的敏感度为67.74%（42/62），特异度为40.00%（8/20），准确度为60.98%（50/82），阳性预测值为77.78%（42/54），阴性预测值为28.57%（8/28）。MSCT动态增强扫描联合后处理技术诊断阳性60例，阴性22例。与手术病理检查比较，MSCT动态增强扫描联合后处理技术诊断的敏感度为83.87%（52/62），特异度为60.00%（12/20），准确度为78.05%（64/82），阳性预测值为86.67%（52/60），阴性预测值为54.55%（12/22）。MSCT动态增强扫描联合后处理技术对结肠癌患者的诊断敏感度、特异度、准确度、阳性预测值、阴性预测值均显著高于MSCT动态增强扫描单独检查（P<0.05）。 结论 结肠癌MSCT动态增强扫描联合后处理技术的诊断价值较MSCT动态增强扫描单独检查高。

[Abstract] Objective To analyze the diagnostic value of MSCT dynamic enhanced scanning combined with post-processing technology in colon cancer. Methods Eighty-two colon cancer patients in the Department of Medical Imaging of Jiujiang NO.1 People′s Hospital from February 2018 to November 2019 were retrospectively selected. All patients were treated with multi-slice spiral computed tomography （MSCT） dynamic enhanced scanning， and all the acquired images were processed by post-processing technology. Results Among the 82 patients， 62 patients were positive and 20 patients were negative in the surgical pathological examination. The MSCT dynamic enhanced scanning was positive in 54 patients and negative in 28 patients. Compared with surgical pathological examination results， the sensitivity of MSCT dynamic enhanced scanning alone was 67.74%（42/62）， the specificity was 40.00%（8/20）; the accuracy was 60.98%（50/82）; the positive predictive value was 77.78%（42/54）; the negative predictive value was 28.57% （8/28）. The MSCT dynamic enhanced scanning combined with post-processing technology was positive in 60 patients and negative in 22 patients. Compared with surgical pathological examination， the sensitivity of MSCT dynamic enhanced scanning combined with post-processing technology was 83.87% （52/62），the specificity was 60.00%（12/20）， the accuracy was 78.05%（64/82）， the positive predictive value was 86.67%（52/60），the negative predictive value was 54.55%（12/22）.The diagnostic sensitivity， specificity， accuracy， positive predictive value and negative predictive value of MSCT dynamic enhanced scanning combined with post-processing were significantly higher than those of MSCT dynamic enhanced scanning alone（P<0.05）. Conclusion The diagnostic value of MSCT dynamic enhanced scanning combined with post-processing technology is higher than that of MSCT alone.
