摘　　要：目的:探讨与分析256排低剂量CT在肺部孤立实性结节灶诊断中的应用。方法:选择2022年2月~2023年10月在龙岩人民医院进行诊治的肺部孤立实性结节灶98例作为研究对象,所有患者均给予256排低剂量CT检查,判断诊断价值。结果:在98例患者中,病理诊断为恶性结节48例(恶性组),其中鳞癌20例,腺癌28例;病理诊断为良性结节50例(良性组),其中错构瘤26例,非特异性炎症4例,硬化性血管瘤6例,炎性假瘤14例。恶性组的分叶征、空泡征、支气管充气征、胸膜凹陷征等占比分别为83.33%、85.42%、83.33%、89.58%,显著高于良性组的44.00%、46.00%、38.00%、44.00%(P<0.05)。恶性组肺动脉主干、肺叶动脉、肺段动脉、肺亚段动脉的CT值与良性组相比均显著提高(P<0.05)。恶性组的图像信噪比、对比噪声比、浓度长度乘积、有效浓度与良性组对比差异不大(P>0.05)。CT诊断为恶性结节49例,良性结节49例,256排低剂量CT在肺部孤立实性结节灶诊断中的应用敏感性、特异性、准确性分别为97.92%(47/48)、96.00%(48/50)、96.94%(95/98)。结论:256排低剂量CT在肺部孤立实性结节灶良恶性诊断中的应用具有很高的敏感性、特异性与准确性,有很好的应用价值。Objective:To explore and analysis the application value of 256 row low-dose CT in the diagnosis of solitary solid nodules in the lungs.Methods:From February 2022 to October 2023,98 cases of solitary solid nodules in the lungs diagnosed and treated at Longyan People’s Hospital were selected as the study subjects.All patients were underwent 256 row low-dose CT examination,recorded the imaging features and assessing diagnostic value.Results:There were 48 cases were diagnosed as malignant nodules(malignant group),included 28 cases of adenocarcinoma and 20 cases of squamous cell carcinoma;Pathological diagnosis showed there were 50 cases of benign nodules(benign group),included 26 cases of hamartomas,14 cases of inflammatory pseudotumors,6 cases of sclerosing hemangiomas,and 4 cases of non-specific inflammation.The proportions of lobulation sign,vacuolar sign,pleural indentation sign,and bronchial inflation sign in the malignant group were 83.33%,85.42%,83.33%,and 89.58%,respectively that were significantly higher than the benign group’s 44.00%,46.00%,38.00%,and 44.00%(P<0.05).The CT values of the main pulmonary artery,lobar artery,segmental artery,and subsegmental artery in the malignant group were significantly higher than those in the benign group(P<0.05).There were no statistically significant difference in the signal-to-noise ratio,contrast noise ratio,concentration length product,effective concentration compared between the malignant group and the benign group(P>0.05).CT diagnosis showed there were 49 cases of malignant nodules and 49 cases of benign nodules.The sensitivity,specificity,and accuracy of 256 row low-dose CT in the diagnosis of solitary solid pulmonary nodules were 97.92%(47/48),96.00%(48/50),and 96.94%(95/98),respectively.Conclusion:The application of 256 row low-dose CT in the diagnosis of benign and malignant solitary pulmonary nodules has high sensitivity,specificity,and accuracy,and has good application value.
