| 摘 要： | 目的:分析局灶性磨玻璃结节(fGGO)MDCT 1mm薄层重建后的表现,得到早期肺癌磨玻璃结节的影像学特征。方法:分析53例已经活检或抗炎治疗证实有病理结果的肺部磨玻璃结节,分析其影像学征象,包括病变位置、大小、形态、界面、边缘、空泡、支气管扩张及蜂窝征、细支气管充气、胸膜凹陷征、血管聚集增粗以及mGGO中GGO含量,统计分析各征象在良恶性之间的差异。结果:良、恶性fGGO边缘、界面以及血管聚集增粗具有统计学差异,P<0.05;而患者的一般资料、病灶基本信息及病灶形态、空泡支气管蜂窝、细支气管充气、胸膜凹陷以及mGGO中GGO含量在良恶性fGGO的表现差异不明显,P>0.05。结论:MDCT 1mm薄层重建后的fGGO影像学特征对于鉴别良恶性fGGO及诊断早期肺癌具有极其重要的应用价值。

| Abstract: | Objective:Analyzing the performance of focal ground glass that under MDCT thin thickness reconstruction, and obtaining CT features of focal ground glass opacity from early stage lung cancer. Method:53 clinically or pathologically confirmed fGGO were collected and analyzed clinical informations and imaging features including lesion location and size, shape, margin, interface, internal density, pleural indentation, vacuole, air bronchus-charging sign and blood vessel clustering. Statistical analyze the differences between the benign and malignant.Results: There were statistical differences between benign and malignant fGGOs in terms of margin (P=0.001), interface (P=0.000)and blood vessel clustering (P=0.009) as well as gender (P=0.120), age (P=0.437), location (P=0.565) size (benign 1.55±0.67) cm, malignant (1.54±0.85) cm,(P=0.978), shape, vacuole (P=0.100), air bronchus-charging sign (P=0.211) and pleural indentation (P=0.243)doesn't significantly found in malignant fGGOs. Conclusion:Margin, interface and blood vessel clustering can make contribute to early lung cancer diagnosis and differentiation of benign and malignant fGGOs. |
