摘　　要：目的:分析胸部螺旋CT低剂量扫描联合MR-DWI在肺结节良恶性鉴别诊断中应用的效果。方法:选取2022年10月—2023年10月枣庄市台儿庄区泥沟镇中心卫生院收治的96例肺结节患者为研究对象,均接受胸部螺旋CT低剂量扫描、MR-DWI检查,以病理检查结果为“金标准”,分析胸部螺旋CT低剂量扫描联合MR-DWI的诊断效能。结果:96例肺结节患者中,病理检查共检出47例恶性;胸部螺旋CT低剂量扫描、MR-DWI联合在肺结节良恶性鉴别中的灵敏度为97.87%、准确率为97.92%高于单独诊断(P<0.05)。恶性肺结节的影像学指标中形态不规则、毛刺征、分叶征、血管集束征、胸膜凹陷征占比高于良性肺结节(P<0.05)。结论:胸部螺旋CT低剂量扫描联合MR-DWI在肺结节良恶性鉴别诊断中具有良好的诊断效能,灵敏度、准确率和阴性预测值较高,且与病理检查结果一致性较高,显著优于单独诊断方法。Objective To analyze the effectiveness of low-dose chest spiral CT combined with MR-DWI in the differential diagnosis of benign and malignant pulmonary nodules.Methods A total of 96 patients with pulmonary nodules admitted to the Central Health Center of Nigou Town,Taierzhuang District,Zaozhuang City from October 2022 to October 2023 were selected as the research subjects.All patients underwent low-dose chest spiral CT scanning and MR-DWI examination,and the pathological examination results were used as the"gold standard"to analyze the diagnostic efficacy of low-dose chest spiral CT scanning combined with MR-DWI.Results Among 96 patients with pulmonary nodules,47 cases were malignant by pathological examination.The sensitivity and accuracy of low dose chest spiral CT combined with MR-DWI in differentiating benign and malignant pulmonary nodules were 97.87%and 97.92%significantly higher than that of single diagnosis(P<0.05).The incidence of irregular shape,burr sign,lobular sign,vascular cluster sign and pleural depression in malignant pulmonary nodules was higher than that in benign pulmonary nodules(P<0.05).Conclusion The combination of low-dose chest spiral CT scan and MR-DWI has good diagnostic efficacy in the differential diagnosis of benign and malignant pulmonary nodules,with high sensitivity,accuracy,and negative predictive value,and high consistency with pathological examination results,significantly superior to individual diagnostic methods.
