摘要：

目的：应用Swensen模型对肺结节进行良恶性分析。方法：回顾分析115例肺结节患者124个肺结节包括48个良性结节、76个恶性结节的资料，比较良恶性结节影像学征像的区别及Swensen系数在两者间的差异。结果：良性结节中形态不规则25例，分叶15例，有毛刺27例，胸膜牵拉征15例，血管集束征12例；恶性结节中形态不规则62例，分叶60例，有毛刺47例，胸膜牵拉征44例，血管集束征67例。在0~10、11~20、21~30 mm的结节中，Swensen系数良性结节分别为0.082 3±0.062 2、0.262 7±0.173 3、0.686 2±0.188 1，恶性结节分别为0.133 8±0.128 8、0.399 9±0.162 9、0.526 9±0.226 9。结论：良恶性结节影像学表现在形态、分叶、胸膜牵拉征与血管集束征上都有明显的差异，但结节所在肺叶的位置及毛刺征表现无明显差异；Swensen系数在0.3~0.6区间时，良恶性结节的区分度较高。

Objective:To analyze the pulmonary nodules with Swensen model. Methods:The data of 124 pulmonary nodules in 115 patients, including 48 benign nodules and 76 malignant nodules, were retrospectively analyzed to compare the differences of imaging features and Swensen coefficient between the two groups. Results:In benign nodules, there were 25 cases of irregular shape, 15 cases of lobulation, 27 cases of spicule sign, 15 cases of pleural dragging signs and 12 cases of vessel convergence.In malignant nodules, there were 62 cases of irregular shape, 60 cases of lobulation, 47 cases of spicule sign, 44 cases of pleural dragging sign and 67 cases of vessel convergence. In nodules of 0-10, 11-20, and 21-30 mm, the Swensen coefficients of benign nodules were 0.082 3±0.062 2, 0.262 7±0.173 3 and 0.686 2±0.188 1, respectively. The Swensen coefficients of malignant nodules were 0.133 8±0.128 8, 0.399 9±0.162 9 and 0.526 9±0.226 9 respectively. Conclusion:The imaging findings of benign nodules and malignant nodules are obviously different in morphology, lobulation, pleural dragging sign and vessel convergence, but there is no significant difference in the location of pulmonary lobe and spicule sign of nodules. When the Swensen coefficient is in the range of 0.3-0.6, the discrimination between malignant tumors and benign tumors can be better made.
