摘　　要：目的:探讨双源CT三期增强扫描检查在诊断原发性肺癌及淋巴结转移中的应用价值。方法:选取2020年5月-2023年12月期间本院收治的均行手术病理检查的106例疑似原发性肺癌患者作为研究对象。患者均接受手术病理检查、CT平扫及双源CT三期增强扫描。以手术病理检查结果作为原发性肺癌及淋巴结转移的“金标准”,分析106例疑似原发性肺癌患者手术病理检查结果。观察CT平扫及双源CT三期增强扫描检查对106例疑似原发性肺癌的诊断结果,且计算其诊断效能及与金标准诊断结果的一致性。结果:106例疑似原发性肺癌患者,经“金标准”确诊恶性96例,良性11例。CT平扫确诊恶性62例,良性6例。双源CT三期增强扫描确诊恶性88例,良性10例。双源CT三期增强扫描检查的灵敏度、特异度及准确度均显著高于CT平扫(P<0.05)。经“金标准”确诊96例恶性病灶均发生淋巴结转移,其中N0期38例、N1期25例、N2期33例。CT平扫确诊52例恶性病灶发生淋巴结转移,双源CT三期增强扫描确诊86例恶性病灶发生淋巴结转移。双源CT三期增强扫描与“金标准”Kappa值显著高于CT平扫(P<0.05)。结论:双源CT三期增强扫描在原发性肺癌及淋巴结转移的诊断具有较高应用价值。与CT平扫对比,前者在原发性诊断中具有较高的准确性和特异性。Objective:To evaluate the value of dual-source CT three-phase enhanced scanning in the diagnosis of primary lung cancer and lymph node metastasis.Methods:106 patients with suspected primary lung cancer admitted to our hospital from May 2020 to December 2023 who underwent surgical pathologic examination were selected as the study objects.All patients underwent pathological examination,CT plain scan and dual-source CT three-phase enhanced scan.Using the results of surgical pathology as the"gold standard"for primary lung cancer and lymph node metastasis,106 patients with suspected primary lung cancer were analyzed.To observe the diagnostic results of 106 patients with suspected primary lung cancer by CT plain scan and dual-source CT three-phase enhanced scan,and calculate the diagnostic efficacy and consistency with the gold standard diagnosis results.Results:Of 106 suspected patients with primary lung cancer,96 cases were malignant and 11 cases were benign.CT plain scan confirmed 62 malignant cases and 6 benign cases.Dual-source CT three-stage enhanced scan confirmed malignant 88 cases and benign 10 cases.The sensitivity,specificity and accuracy of three-phase enhanced dual-source CT scan were significantly higher than those of plain CT scan(P<0.05).Lymph node metastasis was found in 96 cases of malignant lesions confirmed by"gold standard",including 38 cases of N0 stage,25 cases of N1 stage and 33 cases of N2 stage.Plain CT scan confirmed 52 cases of malignant lesions with lymph node metastasis,and dual-source CT three-phase enhanced scan confirmed 86 cases of malignant lesions with lymph node metastasis.The"gold standard"Kappa value of three-phase enhanced dual-source CT scan was significantly higher than that of plain CT scan(P<0.05).Conclusion:Dual-source CT three-phase enhanced scanning has high application value in the diagnosis of primary lung cancer and lymph node metastasis.Compared with CT plain scan,the former has higher accuracy and specificity in primary diagnosis.
