摘　　要：目的:探究多层CT容积扫描与三维重建技术联合在孤立性肺结节的定性鉴别效果。方法:选择2019年7月至2022年8月期间于我院就诊的疑似孤立性肺结节患者150例作为研究对象。所有患者均行多层CT容积扫描及三维重建。以病理结果为“金标准”,分析对比不同性质孤立性肺结节多层CT容积扫描参数、对比单项及联合检查影像学征象检出率、诊断效能及计算一致性。结果:相比于恶性结节,良性结节的灌注峰值时间较长,血容量、增强峰值及表面通透性均显著减少(P<0.05)。多层CT容积扫描联合三维重建技术在孤立性肺结节各征象中检出率均显著高于各单项检查(P<0.05)。多层CT容积扫描联合三维重建技术在孤立性肺结节中的诊断价值均显著高于各单项检查(P<0.05)。kappa检验显示:多层CT容积扫描、三维重建技术一致性均尚可(kappa值=0.484、0.660,P=0.000、0.000);联合检查一致性良好(kappa值=0.946,P=0.000)。结论:在孤立性肺结节诊断中应用多层CT容积扫描与三维重建技术联合诊断临床应用价值较高,能够明确孤立性肺结节性质,同时还可检出不同影像学征象,具有较强的一致性。Objective:To explore the qualitative effect of multi-slice CT volume scanning combined with 3D reconstruction in the identification of isolated pulmonary nodules.Methods:150 patients with suspected solitary pulmonary nodules who were admitted to our hospital from July 2019 to August 2022 were selected as study subjects.All patients underwent multislice CT volume scanning and three-dimensional reconstruction.With pathological results as the"gold standard",the parameters of multi-slice CT volume scanning for isolated pulmonary nodules of different nature were analyzed and compared,and the detection rate of single and combined imaging signs,diagnostic efficiency and calculation consistency were compared.Results:Compared with malignant nodules,the peak perfusion time of benign nodules was longer,and the blood volume,peak enhancement and surface permeability were significantly reduced(P<0.05).The detection rate of multi-slice CT volume scanning combined with 3D reconstruction was significantly higher than that of each single examination(P<0.05).The diagnostic value of multi-slice CT volume scanning combined with 3D reconstruction in isolated pulmonary nodules was significantly higher than that of each single examination(P<0.05).kappa test showed that the consistency of multi-slice CT volume scanning and 3D reconstruction techniques was acceptable(kappa value=0.484,0.660,P=0.000,0.000).The consistency was good(kappa=0.946,P=0.000).Conclusion:The combined diagnosis of multi-slice CT volume scanning and 3D reconstruction technology in the diagnosis of isolated pulmonary nodules has high clinical application value,which can clarify the nature of isolated pulmonary nodules and detect different imaging signs,with strong consistency.
