[摘要] 目的 分析結(jié)腸癌MSCT動態(tài)增強掃描聯(lián)合后處理技術(shù)的診斷價值。 方法 回顧性選取2018年2月至2019年11月九江市第一人民醫(yī)院醫(yī)學影像科結(jié)腸癌患者82例，全部患者均接受多層螺旋電子計算機斷層掃描（MSCT）動態(tài)增強掃描，并將獲取的圖像均經(jīng)后技術(shù)處理。觀察診斷結(jié)果，將手術(shù)病理檢查結(jié)果作為金標準，分析MSCT動態(tài)增強掃描聯(lián)合后處理技術(shù)對結(jié)腸癌患者的診斷效能。 結(jié)果 82例患者中，手術(shù)病理檢查陽性62例，陰性20例;MSCT動態(tài)增強掃描單獨檢查陽性54例，陰性28例。與手術(shù)病理檢查結(jié)果比較，MSCT動態(tài)增強掃描單獨檢查的敏感度為67.74%（42/62），特異度為40.00%（8/20），準確度為60.98%（50/82），陽性預測值為77.78%（42/54），陰性預測值為28.57%（8/28）。MSCT動態(tài)增強掃描聯(lián)合后處理技術(shù)診斷陽性60例，陰性22例。與手術(shù)病理檢查比較，MSCT動態(tài)增強掃描聯(lián)合后處理技術(shù)診斷的敏感度為83.87%（52/62），特異度為60.00%（12/20），準確度為78.05%（64/82），陽性預測值為86.67%（52/60），陰性預測值為54.55%（12/22）。MSCT動態(tài)增強掃描聯(lián)合后處理技術(shù)對結(jié)腸癌患者的診斷敏感度、特異度、準確度、陽性預測值、陰性預測值均顯著高于MSCT動態(tài)增強掃描單獨檢查（P<0.05）。 結(jié)論 結(jié)腸癌MSCT動態(tài)增強掃描聯(lián)合后處理技術(shù)的診斷價值較MSCT動態(tài)增強掃描單獨檢查高。

[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.
