目的:探讨肺结核和肺癌的CT鉴别征象。方法:回顾分析已明确诊断的21例肺结核及51例肺癌病例的CT征象。结果:肺结核多发生于好发部位,形态不一,肿块特征不明显,病灶数目多,易发生钙化和增强效果不明显。肺癌多表现为不规则肿块,呈侵袭性生长,密度不均,明显强化,少见引流支气管,多合并转移征象。结论:根据肺结核和肺癌的CT表现,再结合病史、年龄、吸烟史、其他检查结果和治疗反应,多不难作出鉴别。
Objective: To investigate CT signs of pulmonary tuberculosis and lung cancer. Methods: The CT findings of 21 cases of pulmonary tuberculosis and 51 cases of lung cancer that had been diagnosed were retrospectively analyzed. Results: Pulmonary tuberculosis occurred in the prone area, different morphology, mass characteristics is not obvious, the number of lesions, prone to calcification and enhance the effect is not obvious. More manifestations of lung cancer irregular mass, was invasive growth, uneven density, significantly enhanced rare bronchial drainage, combined with multiple signs of transfer. Conclusion: According to CT findings of pulmonary tuberculosis and lung cancer, combined with history, age, smoking history, other test results and treatment response, it is not difficult to identify more.
