摘　　要：目的:分析局灶性磨玻璃结节(f GGO)MDCT 1 mm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m GGO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 1 mm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。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 f GGO 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 f GGOs 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 f GGOs. Conclusion： Margin, interface and blood vessel clustering can make contribute to early lung cancer diagnosis and differentiation of benign and malignant f GGOs.
