摘　　要：目的:分析CT平扫联合增强扫描诊断胰腺癌(PC)的价值。方法:选取2022年1月—2023年1月济阳区中医医院收治的96例疑似PC患者,患者均行CT平扫与增强扫描,以病理检查为“金标准”,分析CT平扫、增强扫描联合及单一诊断的结果,比较诊断效能;比较PC及非PC患者的CT影像学特征及CT值。结果:96例疑似PC患者中,病理检出78例PC,CT平扫共检出68例,增强扫描共检出71例;CT平扫联合增强扫描共检出77例,CT平扫联合增强扫描诊断PC的灵敏度97.44%、准确率96.88%、阴性预测值89.47%均高于两者单独诊断,差异有统计学意义(P<0.05);Kappa检验显示:CT平扫联合增强扫描与“金标准”的一致性极好(Kappa值=0.900,P<0.001);PC患者的形态为球形、密度不均、平扫密度明显低、门脉期密度低占比高于非PC患者,差异有统计学意义(P<0.05)。PC患者胰腺病变的平扫、动脉期、静脉期的CT值低于非PC患者,差异有统计学意义(P<0.05)。结论:CT平扫联合增强扫描可有效诊断出胰腺癌,具有一定的应用价值,可推广应用。Objective To analyze the value of CT plain scan combined with enhanced scan in the diagnosis of pancreatic cancer(PC).Methods A total of 96 patients with suspected PC admitted to Jiyang District Hospital of Traditional Chinese Medicine from January 2022 to January 2023 were selected.All patients underwent CT plain scan and enhanced scan.Pathology approaches were taken as the"gold standard"to analyze the results of combined CT plain scan and enhanced scan and single diagnosis,and compare the diagnostic efficacy.CT imaging features and CT values were compared between PC and non-PC patients.Results Among the 96 suspected patients with PC,78 cases were confirmed by pathology,68 cases were detected by plain CT scan and 71 cases were detected by enhanced CT scan.A total of 77 cases were detected by CT plain scan combined with enhanced scan.The sensitivity,accuracy and negative predictive value of CT plain scan combined with enhanced scan in the diagnosis of PC were 97.44%,96.88%and 89.47%,all of which were significantly higher than those diagnosed by CT alone,and the differences were statistically significant(P<0.05).Kappa test showed that CT plain scan combined with enhanced scan had excellent consistency with the"gold standard"(Kappa value=0.900,P<0.001).The shape of PC patients was spherical,the density was uneven,the plain scan density was obviously low,and the proportion of low density in portal pulse stage was higher than that in non-PC patients,the difference was statistically significant(P<0.05).The CT values of plain scan,arterial stage and venous stage of pancreatic lesions in PC patients were lower than those in non-PC patients,and the difference was statistically significant(P<0.05).Conclusion CT plain scan combined with enhanced scan can effectively diagnose pancreatic cancer,which has certain application value and can be popularized.
