摘要
目的:探讨电子计算机X射线断层扫描(CT)与数字化X线摄影(DR)对肺癌的诊断价值及临床意义。方法:选取舞钢市人民医院2020年4月—2022年2月就诊的142例疑似肺癌患者作为研究对象,入院后均行CT及DR检查。以手术及病理诊断结果为“金标准”,统计两种方案影像学特征检出情况,并分析两种方案的诊断效能情况。结果:与DR检查比较,CT检查对肺癌毛刺征、分叶征、空泡征、血管聚集、胸膜凹陷、厚壁空洞、支气管气象征象的检出率较高,差异有统计学意义(F=12.399、12.783、14.525、20.405、19.338、13.078、5.135,P<0.05)。与CT、DR检查单独诊断肺癌比较,二者联合诊断灵敏度及准确率较高,漏诊率较低,差异有统计学意义(χ^(2)=14.552、10.804、14.552,P<0.05);与CT、DR检查单独诊断比较,联合诊断纵隔淋巴结转移灵敏度及准确率较高,漏诊率较低,差异有统计学意义(χ^(2)=11.241、8.827、11.241,P<0.05)。结论:CT、DR检查对于早期肺癌均具有一定诊断价值,二者联合应用可显著提高诊断准确率,为临床术前诊断及病情评估提供参考,以制定针对性的手术方案。
Objective:To investigate the diagnostic value and clinical significance of electronic computed tomography(CT)and digital radiography(DR)for lung cancer.Methods:142 patients with suspected lung cancer attending the hospital from April 2020 to February 2022 were selected for the study,and CT and DR examinations were performed upon admission.Using the surgical and pathological findings as the“gold standard”,the detection of imaging features of the two protocols was counted,and the diagnos-tic efficacy of the two protocols was analyzed.Results:Compared with DR examination,CT examination had a higher detection rate of lung cancer burr sign,lobar sign,vacuolar sign,vascular aggregation,pleural depression,thick-walled cavity,and bronchial meteorological signs,with statistically significant differences(F=12.399,12.783,14.525,20.405,19.338,13.078,5.135,P<0.05).Compared with CT and DR examinations alone for the diagnosis of lung cancer,the combined diagnosis of the two had higher sensi-tivity and accuracy and lower leakage rate,with statistically significant differences(χ^(2)=14.552,10.804,14.552,P<0.05).Com-pared with CT and DR examinations alone,the combined diagnosis of mediastinal lymph node metastasis was more sensitive and accurate,and the leakage rate was lower,with statistically significant differences(χ^(2)=11.241,8.827,11.241,P<0.05).Conclu-sion:CT and DR examination have certain diagnostic value for early stage lung cancer,and their combined application can signifi-cantly improve the diagnostic accuracy and provide reference for clinical preoperative diagnosis and disease assessment,so as to formulate targeted surgical plans.
