肺纹移位在肺内小结节CT定性诊断中的意义

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。

Significance of lung marking shift in the qualitative diagnosis of intrapulmonary nodules with CT

Objective To study the value of lung marking shift in the qualitative diagnosis of intrapulmonary nodules with CT.Methods CT findings of lung marking shift in 43 patients with clinically and pathologically proved solitary intrapulmonary nodules whose diameter less than 3 cm were retrospectively analyzed by combining the orderliness degree of focal borders so as determining the relationship between lung marking shift and lesion's qualities.Results The lesions with lung marking shift seen on pulmonary window were found in 30 cases(70.4 % ),of them,lung marking gathering was 23 cases,and lung marking pushing pressuring was 7 cases.Eight cases with lung marking gathering and smooth and complete focal borders all were found to be inflammatory lesions while 7 cases with lung marking pushing pressuring all were found to be non- inflammatory lesions.Conclusion Lung marking shift can be regarded as one of reference signs in the qualitative diagnosis of intrapulmonary nodules.
