　　[摘要] 目的 研究直接底只X线摄影系统联合多层螺旋CT（MSCT）在肺胰癌病理分期中的应用价值。 方法 选取2020年10月至2021年3月在我院进行检查的疑似肺胰癌患者100例，经临床指南结合临床特征检查确诊例数为97例。采用直接数字化X线摄影系统、MSCT对患者进行检查;并分析对肺胰癌诊断中的应用价值。 结果 ①X线摄影检出肺胰癌病理分期影像特征的百分率为65.97%（64/97），MSCT检查检出肺胰癌病理分期影像特征的百分率为76.28%（74/97），两项检查检出肺胰癌病理分期影像特征的百分率为98.96%（96/97），两项检查的检出率较高（χ2=35.082，P=0.001）。②X线摄影检出肺胰癌影像特征的百分率为75.25%（73/97），MSCT检查检出肺胰癌影像特征的百分率为83.50%（81/97），两项检查检出神肺胰癌影像特征的百分率为97.93%（95/97），两项检查的检出率较高（χ2=20.720，P=0.001）。③以临床指南结合临床特征表现为诊断金标准，结果显示，与X线摄影、MSCT相比，两项检查对肺胰癌病理分期的诊断敏感度、准确度较高，差异有统计学意义（P<0.05）。ROC曲线结果显示，两项联合对肺胰癌病理分期的鉴别价值较高，差异有统计学意义（P<0.05）。 结论 直接数字化X线摄影系统联合MSCT在肺胰癌病理分期中的诊断价值较为理想，可用于肺胰癌病理分期的临床诊断。

　　[Abstract] Objective To study the application value of direct digital X-ray imaging technology combined with multi-layer spiral CT（MSCT） in the pathological staging of lung and pancreatic carcinoma. Methods A total of 100 patients with suspected lung and pancreatic carcinoma who were examined in our hospital from October 2020 to March 2021 were selected as the study subjects， and 97 of them were definitely diagnosed by clinical guidelines combined with clinical features. The patients were examined by direct digital X-ray imaging technology and MSCT， and the application value of the combination of the two in the diagnosis of lung and pancreatic carcinoma was analyzed. Results ①The detection rate of imaging features of pathological staging of lung-pancreatic carcinoma by X-ray was 65.97%（64/97） and that detected by MSCT was 76.28%（74/97）， and the detection rate by the two methods together was 98.96% （96/97）， indicating that the detection rate by the two methods together was higher（χ2=35.082，P=0.001）. ② The detection rate of imaging features of lung-pancreatic carcinoma by X-ray was 75.25%（73/97） and that detected by MSCT was 83.50% （81/97）， and the detection rate by the two methods together was 97.93%（95/97）， indicating that the detection rate by the two methods together was higher（χ2=20.720，P=0.001）. ③The gold standard of diagnosis was clinical guidelines combined with clinical features. The results showed that the sensitivity and accuracy of the combination of the two methods in the diagnosis of pathological staging of lung and pancreatic carcinoma were higher than those of X-ray and MSCT alone， with statistically significant differences（P<0.05）. The receiver operating characteristic curve （ROC） showed that the combination of the two methods had a higher differential value in the pathological staging of lung and pancreatic carcinoma， with statistically significant difference（P<0.05）. Conclusion The direct digital X-ray imaging technology combined with MSCT has ideal diagnostic value in the pathological staging of lung and pancreatic carcinoma， and can be used in clinical diagnosis of pathological staging of pulmonary and pancreatic carcinoma.
