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 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 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.
