薄层三维重建联合个性化扫描对良、恶性实性孤立性肺结节的诊断价值研究

Diagnostic value of thin-layer three-dimensional reconstruction technology combined with personalized scanning for benign and malignant solid solitary pulmonary nodules

目的:探讨薄层三维重建联合个性化扫描对良、恶性实性孤立性肺结节的诊断价值。方法:回顾性分析江山市人民医院2020年1月至2021年7月诊治的实性孤立性肺结节患者140例的临床资料,其中良性组40例,恶性组100例。患者均接受薄层三维重建联合个性化扫描。比较良、恶性实性孤立性肺结节患者薄层三维重建联合个性化扫描的肺结节征象和诊断性能的差异。结果:恶性组有空洞征、分叶征、血管集束征、空泡征、牵拉肺气肿、贴近胸膜和远端穿行血管征的比例分别为11.0%、81.0%、77.0%、49.0%、6.0%、10.0%、31.0%,与良性组的42.5%、62.5%、55.0%、27.5%、20.0%、32.5%、5.0%相比,差异均有统计学意义(χ^(2)=15.80、5.00、5.66、4.55、4.76、8.96、9.33,均P<0.05);敏感性最高的征象为分叶征,鉴别良、恶性肺结节的效能最高,达82.0%。结论:良、恶性实性孤立性肺结节患者空洞征、分叶征、血管集束征、空泡征、牵拉肺气肿、贴近胸膜和远端穿行血管征存在明显差异,分叶征为敏感性最高的征象。薄层三维重建联合个性化扫描对肺结节良、恶性具有诊断价值。

Objective:To investigate the diagnostic value of thin-layer three-dimensional reconstruction technology combined with personalized scanning for benign and malignant solid solitary pulmonary nodules.Methods:The clinical data of 140 patients with solid solitary pulmonary nodules admitted to Jiangshan People's Hospital form January 2020 to July 2021 were retrospectively analyzed.These patients consisted of 40 patients with benign solid solitary pulmonary nodules(benign group)and 100 patients with malignant solid solitary pulmonary nodules(malignant group).All patients underwent thin-layer three-dimensional reconstruction combined with personalized scanning.The pulmonary nodule signs achieved by thin-layer three-dimensional reconstruction combined with personalized scanning and the diagnostic performance of the combined technology were compared between benign and malignant groups.Results:The proportions of patients with lung cavity sign,lobular sign,vascular convergence sign,vacuole sign,emphysema distribution sign,split pleura sign,and distal perforating vascular sign in the malignant group were 11.0%,81.0%,77.0%,49.0%,6.0%,10.0%and 31.0%,respectively,and they were 42.5%,62.5%,55.0%,27.5%,20.0%,32.5%,and 5.0%,respectively in the benign group(χ^(2)=15.80,5.00,5.66,4.55,4.76,8.96,9.33,all P<0.05).The most sensitive sign was lobular sign,which had the highest efficiency,up to 82.0%,in differentiating benign and malignant pulmonary nodules.Conclusion:Lung cavity sign,lobular sign,vascular convergence sign,vacuole sign,emphysema distribution sign,split pleura sign,and distal perforating vascular sign differ greatly between patients with benign and malignant solid solitary pulmonary nodules.Lobular sign has the highest sensitivity in differentiating benign and malignant solid solitary pulmonary nodules.Thin-layer three-dimensional reconstruction combined with personalized scanning has a diagnostic value for benign and malignant solid solitary pulmonary nodules.
