肺结节CT靶扫描及重建技术对肺腺癌支气管改变的诊断价值分析

Value Analysis of Pulmonary Nodules CT Target Scanning and Reconstruction in Diagnosis of Bronchial Changes of Lung Adenocarcinoma

目的分析对肺腺癌支气管改变患者行肺结节CT靶扫描及重建技术的临床诊断意义。方法将2018年6月至2019年8月在本院的50例肺腺癌及癌前病变患者作为研究对象,所有患者均经过手术或病理诊断确诊,共有56个病灶。对所有患者实施肺结节CT靶扫描及重建技术进行诊断,分析患者的诊断结果。结果经CT检查之后显示56个病灶中有49(87.5%)个存在支气管改变,再49个病灶中包括不典型腺瘤样增生病灶、原位癌病灶、微浸润腺癌病灶与浸润型腺癌病灶,分别有1个、25个、14个、9个。而经过常规CT平扫仅仅提示存在支气管改变的病灶有38个,占比67.86%,与CT靶扫描的检测结果差异存在统计学意义(P<0.05);同时经过常规平扫与靶扫描均发现患者存在肺结节支气管扩张、肺结节支气管远侧变尖、肺结节支气管受压、肺结节支气管阻断、肺结节支气管狭窄等变化。结论肺结节CT靶扫描及重建技术有助于提示肺腺癌患者的支气管变化情况,尤其是能够尽早发现支气管壁增厚情况,能提升初期肺腺癌患者的确诊率,临床应用价值高,值得推广。

Objective To analyze clinical significance of CT target scanning and reconstruction of pulmonary nodules of bronchial changes of lung adenocarcinoma patients.Methods:The paper chose 50 patients with lung adenocarcinoma and precancerous lesions in our hospital from June 2018 to August 2019 as research objects,based on operation or pathology diagnosis with CT target scan and reconstruction technique,with 56 lesions in total.Diagnosis effect was analyzed.Results:After CT examination,49(87.5%)of 56 lesions were found bronchopathy,and 49 lesions included atypical adenomatous hyperplasia,in situ,microinvasive and invasive adenocarcinoma,including 1,25,14 and 9 lesions.However,routine CT scanning found 38 lesions with bronchopathy,accounting for 67.86%,with significant difference between routine CT scanning and CT target scaning,(P<0.05);both routine CT scanning and CT target scaning showed,patients had changes of bronchodilation,sharp distal end of bronchus of pulmonary nodule,bronchial compression of pulmonary nodules,bronchial block of pulmonary nodules,and bronchial stenosis of pulmonary nodules.Conclusion:CT target scaning and reconstruction of pulmonary nodules can indicate changes of bronchus of lung adenocarcinoma patients,can detect bronchial wall thickening as early as possible,improve diagnosis rate of patients at early stage,which is worthy of promotion.
