摘要：

目的 探讨普通放射和CT 在肺部孤立性球形病变诊断方面的临床效果。方法 回顾性分析2015年9月至2017年2月本院收治肺部孤立性球形病变患者60例的临床资料，所有患者均进行X 线检查和CT检查，观察评估两种检查方法对于患 者病变的诊断结果。结果 在单一病变中，CT检查对肺癌的检出正确率高于X 线检查（P<0.05）；两种检查方法对肺部炎性病 变、良性肿瘤、肺结核、其他的检出正确率比较，无显著差异（P>0.05）。CT 检查的总检出正确率高于X 线检查（P<0.05）。CT 对 于肺部孤立性球形病变的诊断灵敏度为97.92%（47/48）、特异度为83.33%（10/12）；X线对肺部孤立性球形病变的诊断灵敏 度为70.83%（34/48）、特异度为75.00%（9/12）；两种检查方式的诊断特异度并无明显差异（P>0.05），但CT检查对于肺部孤立 性球形病变的诊断灵敏度明显高于X 线检查（P<0.05）。结论 同X线检查相比，在肺部孤立性球形病变诊断中应用CT 检查 可取得更为清晰的影像学结果，不仅可有效反映病灶的形态特征，同时借助对病灶血流灌注情况的评估可有效鉴别病灶良 恶性，对于早期治疗的顺利开展具有十分积极的作用，建议在临床进一步推广应用。

ABSTRACT: Objective To evaluate the clinical effect of CT and X ray examination in the diagnosis of pulmonary solitary spherical lesions. Methods The clinical data of 60 patients with solitary sphenoid pulmonary disease in our hospital from September 2015 to February 2017 were retrospectively analyzed. All patients underwent X ray examinations and CT examinations. The diagnostic results of the two examinations were observed and evaluated. Results In the single lesion diagnose, the accuracy rate of CT examination for lung cancer was higher than that of the X-ray examination (P<0.05); there were no significant differences between the two methods in the diagnose of pulmonary inflammatory lesions, benign tumors, tuberculosis, and others (P>0.05). The overall positive rate of CT examination was higher than that of the X-ray examination (P<0.05). The diagnostic sensitivity and specificity of CT was 97.92% (47/48) and 83.33% (10/12) respectively in pulmonary solitary spherical lesions, which was 70.83% (34/48), 75.00% (9/12) of the X-ray examination; there was no significant in the diagnostic specificity of the two methods (P>0.05), but the diagnostic sensitivity of CT was higher than that of the X-ray examination (P<0.05). Conclusion Compared with the X ray examination, CT examination can be used to obtain more clear imaging results in the diagnosis of solitary spheroid solitary pulmonary disease, which not only can effectively reflect the morphological characteristics of the lesion, at the same time effectively identify the benign and malignant lesions, it has significance in the smooth implementation of early treatment, and it is proposed to further promote the clinical application.
