目的：探讨应用最大似然法鉴别周围性肺癌、肺错构瘤及结核球3种孤立性肺结节(SPN)的诊断价值。
Objective: to evaluate the diagnostic values of discrimination method of large log-likelihood study in differentiating the 3 kinds of SPN among peripheral lung carcinoma, hamartoma and tuberculoma.
目的：了解经支气管肺活检（TBLB）对疑为周围型肺癌的肺部孤立性肿块的诊断作用。
Objective: To evaluate the diagnostic value of TBLB in peripheral pulmonary nodule that was not defined.
结果124例中包括周围型肺癌74例，中央型肺癌42例，炎性假瘤4例，结核瘤2例，淋巴瘤1例，软骨瘤型错构瘤1例。
Results Of 124 cases, there were 74 cases with peripheral pulmonary carcinoma, 42 centric pulmonary carcinoma, 4 inflammatory pseudotumor, 2 tuberculosis, 1 lymphoma and 1 chondromatous hamartoma.
结论结核瘤动态增强CT扫描在强化值、时间一密度曲线及强化形态均有一定特征，可与周围型肺癌及炎性肿块相鉴别。
Conclusion: Tuberculoma can be differentiated from peripheral pulmonary carcinoma or inflammatory mass by the characteristic of maximum enhanced ct value, enhanced pattern and time-attenuation curves.
结论同层动态ct增强扫描有利于周围型肺癌性与肺结核性结节的定性诊断。
Conclusions Single-location dynamic CT is helpful in differential diagnosis of peripheral pulmonary carcinoma and tuberculoma.
