摘　　要：目的:对比3.0T磁共振UTE序列与CT在肺结节显示能力上及其临床应用价值。方法:选取信阳市中心医院2021年1月至2023年12月收治的100例肺结节患者,均行3.0T磁共振UTE序列扫描以及CT平扫,以CT检出的结果作为金标准,比较CT平扫和3.0T磁共振UTE序列的结节性质检出情况、主要征象显示情况,采用ROC曲线及决策树模型综合评估3.0 T磁共振UTE序列肺结节良恶性的鉴别价值。结果:100例患者,CT平扫显示肺结节132枚,3.0T磁共振UTE序列显示结节129枚,3.0T磁共振UTE序列实性结节、亚实性结节、磨玻璃结节检出率与CT平扫比较,均无统计学意义(P﹥0.05)。3.0T磁共振UTE序列对分叶征、毛刺征、胸膜牵拉显示率与CT平扫比较,均无统计学意义(P﹥0.05),3.0T磁共振UTE序列对结节内部混杂显示率高于CT平扫(P<0.05)。CT平扫显示恶性结节11枚,3.0T磁共振UTE序列显示恶性结节9枚,ROC分析显示,3.0T磁共振UTE序列鉴别肺结节良恶性的ROC曲线的AUC为0.860,约登指数为0.719,敏感度、特异度分别为72.7%、99.2%,95%CI为(0.700,1.000)。以CT平扫结果为因变量,以3.0T磁共振UTE序列结果为自变量,构建3.0T磁共振UTE序列鉴别肺结节良恶性的决策树图模型,误判率为3.0%,预测准确率97.0%。结论:3.0磁共振UTE序列对肺结节的检出与CT平扫相当。Objective:To compare the clinical application value of 3.0T magnetic resonance UTE sequence and CT in displaying pulmonary nodules.Methods:100 patients with pulmonary nodules from January 2021 to December 2023 in Xinyang Central Hospital were selected for 3.0T magnetic resonance UTE sequence scanning and CT plain scan.The results detected by CT were used as the gold standard to compare the detection of nodule properties and the display of main signs between CT plain scan and 3.0T magnetic resonance UTE sequence.The ROC curve and decision tree model were used to comprehensively evaluate the value of 3.0T magnetic resonance UTE sequence in differentiating benign and malignant pulmonary nodules.Results:Among 100 patients,CT plain scan showed 132 pulmonary nodules,while 3.0T magnetic resonance UTE sequence showed 129 nodules.The detection rates of solid nodules,sub solid nodules and ground glass nodules in 3.0T magnetic resonance UTE sequence were not statistically significant compared to CT plain scan(P>0.05).The display rates of lobulation,spiciness and pleural traction on the 3.0T magnetic resonance UTE sequence were not statistically significant compared to CT plain scan(P>0.05),while the display rates of internal mixed nodules on the 3.0T magnetic resonance UTE sequence were higher than those on CT plain scan(P<0.05).CT plain scan showed 11 malignant nodules,while 3.0T magnetic resonance UTE sequence showed 9 malignant nodules.ROC analysis showed that the AUC of the ROC curve for distinguishing benign and malignant pulmonary nodules using 3.0T magnetic resonance UTE sequence was 0.860,and the Jordan index was 0.719.The sensitivity and specificity were 72.7%,99.2%,and 95%confidence intervals were(0.700,1.00),respectively.Using CT plain scan results as the dependent variable and 3.0T magnetic resonance UTE sequence results as the independent variable,a decision tree model for distinguishing benign and malignant pulmonary nodules using 3.0T magnetic resonance UTE sequence was constructed.The misjudgment rate was 3.
