摘要
目的分析不同病理类型肺部磨玻璃结节的HDCT征象。方法回顾性分析经手术病理证实的肺部磨玻璃结节患者共57例,其中良性病变组16例,浸润前病变组17例,浸润性病变组24例。双盲阅片分析结节位置、大小、内部实性成分、形状以及边缘形态。计量资料采用单因素方差分析;计数资料采用x^2检验或Fisher确切概率法;对良恶性病变大小及实性成分的鉴别做ROC曲线分析。结果患者性别、年龄以及病灶位置分布无明显统计差异(P值均>0.05);而病灶大小、内部实性成分、病灶形状及边缘形态差异有统计学意义(P值均<0.05)。鉴别良恶性病变大小的临界值为11.05mm,敏感度87.5%,特异度78.8%;实性成分大小临界值为4.55mm,敏感度70.8%,特异度90.9%。结论对于表现为磨玻璃密度的肺结节而言,病灶大小、内部实性成分、形状及边缘形态对于鉴别病灶良恶性有一定的预测价值。
Objective To discuss the pathological classification and imaging characteristics of lung ground-glass opacity（ GGO）. Methods Fifty-seven patients with GGO on HDCT which were resected and confirmed pathologically were retrospectively recruited. There were 16 benign lesions,17 preinvasive leisions and 24 invasive lesions. Lesion location,size,solid component,shape,and margin were analyzed. Mono factor analysis of variance was used to deal with the measursement data. Enumeration data were analyzed by Chi-square test or Fisher＇s exact test. The size and solid component were assessed using ROC curves. Results There were no significant statistical differences in gender,age and lesion location（ P〈0. 05）. lesion size,solid component,whereas,shape and margin were significantly different between each group（ P〈0. 05）. ROC curve showed that when diameter of lesion size was more than 11. 05 mm,the sensitivity and specificity were 87. 5% and 78. 8%,respectively.When the solid component of different group was more than 4. 55 mm,the sensitivity and specificity were 70. 8% and 90. 9%,respectively. Conclusion The lesion size,solid component,shape and margin can help predict the status of GGO.
