[摘要] 目的 分析結(jié)腸癌MSCT動(dòng)態(tài)增強(qiáng)掃描聯(lián)合后處理技術(shù)的診斷價(jià)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(xué)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(jì)算機(jī)斷層掃描（MSCT）動(dòng)態(tài)增強(qiáng)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(biāo)準(zhǔn)，分析MSCT動(dòng)態(tài)增強(qiáng)掃描聯(lián)合后處理技術(shù)對(duì)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(yáng)性62例，陰性20例;MSCT動(dòng)態(tài)增強(qiáng)掃描單獨(dú)檢查陽(yáng)性54例，陰性28例。與手術(shù)病理檢查結(jié)果比較，MSCT動(dòng)態(tài)增強(qiáng)掃描單獨(dú)檢查的敏感度為67.74%（42/62），特異度為40.00%（8/20），準(zhǔn)確度為60.98%（50/82），陽(yáng)性預(yù)測(cè)值為77.78%（42/54），陰性預(yù)測(cè)值為28.57%（8/28）。MSCT動(dòng)態(tài)增強(qiáng)掃描聯(lián)合后處理技術(shù)診斷陽(yáng)性60例，陰性22例。與手術(shù)病理檢查比較，MSCT動(dòng)態(tài)增強(qiáng)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(zhǔn)確度為78.05%（64/82），陽(yáng)性預(yù)測(cè)值為86.67%（52/60），陰性預(yù)測(cè)值為54.55%（12/22）。MSCT動(dòng)態(tài)增強(qiáng)掃描聯(lián)合后處理技術(shù)對(duì)結(jié)腸癌患者的診斷敏感度、特異度、準(zhǔn)確度、陽(yáng)性預(yù)測(cè)值、陰性預(yù)測(cè)值均顯著高于MSCT動(dòng)態(tài)增強(qiáng)掃描單獨(dú)檢查（P<0.05）。 結(jié)論 結(jié)腸癌MSCT動(dòng)態(tài)增強(qiáng)掃描聯(lián)合后處理技術(shù)的診斷價(jià)值較MSCT動(dòng)態(tài)增強(qiáng)掃描單獨(dú)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.
