| 摘 要： | 目的评价多层螺旋CT(MSCT)扫描形态学对肺内恶性结节的诊断价值。资料与方法69例肺内恶性结节患者行MSCT扫描,应用多种后处理技术全面了解病灶形态学特征,运用Spearman相关分析探讨病灶形态学特征与病理特征的关系。筛选出有意义的形态学征象后,与同期86例经手术证实的非恶性结节形态学数据行χ2检验,比较两组形态学征象构成比的差别。结果恶性病变中胸膜凹陷征、支气管截断征与血管聚集征出现率分别为81.8%、85.5%和95.7%;分化程度与空泡征呈显著正相关(r值为0.631),P-TNM分期与毛刺征呈显著正相关(r值为0.652),结节大小与衰减密度呈显著负相关(r值为-0.714),P值均为0.000。空泡征、短毛刺、非实性结节、胸膜凹陷征、支气管截断征与血管聚集征在恶性结节中的出现率均明显高于非恶性结节。结论多种后处理技术应用于MSCT中能全面了解病灶特征,空泡征、短毛刺、非实性结节、胸膜凹陷征、支气管截断征与血管聚集征是提示恶性结节的征象。

| Abstract: | Objective To assess the diagnostic values of multi-slice spiral CT imaging in pulmonary malignant nodules. Materials and Methods 69 Cases of pulmonary malignant nodules were underwent CT perfusion? scan by 16-slice spiral CT. The three-dimensional reconstruction technique of multi-slice spiral CT was performed to evaluate the morphologic features. Multiple correlation analysis was used to study the relationship between CT morphologic features and clinical pathological features in pulmonary malignant nodules... |
