目的探讨肺纹移位在肺结节CT定性诊断中的价值。方法对43例有随访病理结果或经临床证实直径小于3cm肺内孤立性结节进行回顾性分析,结合病灶边缘光整度研究肺纹移位与病灶性质的关系。结果用肺窗观察到有肺纹移位现象的病灶共30例,占70.4%,肺纹聚拢23例,推移7例,其中肺纹聚拢且病灶边缘光整的共8例全部为炎性病灶。肺纹推移的7例全部为非炎性病灶。结论肺纹移位现象可以作为肺结节定性诊断的参考征象之一。
Objective To investigate the value of lung pattern shift in the qualitative diagnosis of pulmonary nodules. Methods A retrospective analysis was performed on 43 cases with pathological findings or clinically confirmed solitary pulmonary nodules less than 3 cm in diameter. The relationship between lung stripe displacement and the nature of the lesion was studied in combination with the edge radii of the lesion. Results There were 30 lesions (70.4%) with lung pattern shift, 23 lesions (with lung pattern) and 7 lesions (lesions) with 8 lesions . All of the 7 cases of lung pattern shift were non-inflammatory lesions. Conclusion Pulmonary pattern shift can be used as a qualitative diagnosis of pulmonary nodules, one of the reference signs.
