摘要
目的 分析CT灌注成像参数对周围型肺癌、肺炎性肿块的鉴别诊断价值.方法 100 例肺部病变患者经病理检查确诊为周围型肺癌 49 例,肺炎性肿块 51 例,比较不同疾病类型患者的CT灌注成像参数PS、BV、MTT,分析PS、BV、MTT单独及联合鉴别诊断周围型肺癌、肺炎性肿块的效能.结果 周围型肺癌患者的PS、BV、MTT均高于肺炎性肿块患者(P<0.05).ROC曲线显示,PS、BV、MTT联合鉴别诊断周围型肺癌、肺炎性肿块的AUC高于各参数单独鉴别诊断.结论 CT灌注成像参数对周围型肺癌、肺炎性肿块的鉴别诊断价值较高,值得临床推广应用.
Abstract
Objective To analyze the value of CT perfusion imaging parameters in the differential diagnosis of peripheral lung cancer and lung inflammatory masses.Methods Among 100 patients with lung lesions,49 cases were diagnosed as peripheral lung cancer and 51 cases as lung inflammatory masses by pathological examination.The CT perfusion imaging parameters PS,BV and MTT of patients with different disease types were compared,and the efficiencies of single and combination of PS,BV and MTT in the differential diagnosis of peripheral lung cancer and lung inflammatory masses were analyzed.Results The PS,BV and MTT of patients with peripheral lung cancer were higher than those of patients with lung inflammatory masses(P<0.05).ROC curve showed that the AUC of combination of PS,BV and MTT in the differential diagnosis of peripheral lung cancer and lung inflammatory masses was higher than that of each parameter alone.Conclusions CT perfusion imaging parameters in the differential diagnosis of peripheral lung cancer and lung inflammatory masses have high value,which are worthy of clinical promotion and application.
