      【摘要】 目的 分析多层螺旋CT低剂量胸部扫描对肺结节的诊断价值。方法 将2017年2月至2019年1月期间西安市第三医院收治的100例胸部X片检查疑为肺癌患者作为研究对象，所有患者均分别接受胸部X片检查与低剂量螺旋CT扫描。以病理学结果为标准，比较两种检查方式对肺癌及肺腺癌诊断效能的差异。结果 低剂量螺旋CT对肺癌与肺腺癌的诊断灵敏度分别为98.91%、93.55%、特异性分别为87.50%、94.74%，明显高于胸部X片对肺癌与肺腺癌的诊断灵敏度(76.47%、53.70%)、特异性(46.67%、78.26%)，差异均有统计学意义(P<0.05)；低剂量螺旋CT对肺癌与肺腺癌的诊断符合率分别为96.81%和90.63%，明显高于胸部X片的69.15%和45.31%，差异均有统计学意义(P<0.05)。结论 低剂量螺旋CT针对肺癌与肺腺癌的诊断效能较高，对患者疾病的鉴别具有重要价值，其诊断结果可为患者后续治疗方案的制定提供依据。

【Abstract】 Objective To analyze the diagnostic value of low-dose multislice spiral computed tomography(CT) in pulmonary nodules. Methods From February 2017 to January 2019, 100 patients suspected to be lung cancerby chest X-ray in Xi'an No.3 Hospital were selected as the research subjects. All patients received chest X-ray andlow-dose multislice spiral CT. Based on pathological results, the diagnostic efficacy of the two methods for lung cancerand adenocarcinoma were compared. Results The sensitivity and specificity of the diagnosis of lung cancer and lungadenocarcinoma for low-dose multislice spiral CT were 98.91% and 93.55%, 87.50% and 94.74%, respectively, whichwere significantly higher than corresponding 76.47% and 53.70%, 46.67% and 78.26% for chest X-ray (all P<0.05). Thediagnostic coincidence rates of lung cancer and lung adenocarcinoma for low-dose multislice spiral CT were 96.81% and90.63% respectively, which were significantly higher than corresponding 69.15% and 45.31% for chest X-ray (P<0.05).Conclusion Low-dose multislice spiral CT has a high diagnostic efficiency for lung cancer and lung adenocarcinoma,and it has an important value in the differentiation of patients' diseases. Its diagnostic results can provide a basis for thedevelopment of follow-up treatment plan for patients.
