摘　　要：目的探究对肺内占位良恶性病变患者应用多层螺旋CT多平面重建后处理技术(MDCT-MPR)行鉴别诊断的效果。方法随机选取2018年12月至2020年12月本院肿瘤科接收肺内占位性疾病患者200例作为研究对象,本院对纳入患者均应用常规CT检查及MDCT-MPR检查,分析诊断结果。结果经临床病理诊断,纳入患者中,良性病变102例(良性组),恶性病变98例(恶性组)。恶性组患者常规CT征象发生率均高于良性组(P<0.05)。患者均可由MDCT-MPR显示肺部动脉,不同重建方法重建评分对比(P>0.05);肺内占位良恶性患者MDCT-MPR诊断敏感性93.14%(95/102)、特异性92.86%(91/98)、阳性预测值93.14%(95/102)、阴性预测值92.86%(91/98)。结论肺内占位良恶性患者鉴别诊断中,应用MDCT-MPR效果显著,图像清晰,可有效反应肺内占位状况,提供诊治依据,值得推广。Objective to explore the effect of mdct-mpr in differential diagnosis of benign and malignant lung lesions.Methods 200 patients with lung occupying diseases received by our oncology department from December 2018 to December 2020 were randomly selected as the research object.The patients included in the hospital were randomly selected by routine CT and MDCT MPR examination,and the diagnosis results were analyzed.Results According to the clinical and pathological diagnosis,102 cases of benign lesions(benign group)and 98 cases of malignant lesions(malignant group)were included.The incidence of conventional CT signs in malignant group was higher than that in benign group(P<0.05).Mdct-mpr showed the pulmonary artery in all patients,and the reconstruction scores of different reconstruction methods were compared(P>0.05).The sensitivity,specificity,positive predictive value and negative predictive value of mdct-mpr were 93.14%(95/102),92.86%(91/98),93.14%(95/102)and 92.86%(91/98)respectively.Conclusion In the differential diagnosis of benign and malignant pulmonary space occupying patients,the application of mdct-mpr has significant effect and clear image,which can effectively reflect the status of pulmonary space occupying,provide the basis for diagnosis and treatment,and is worthy of promotion.
