摘要
目的探讨肺肿瘤的毛刺征和肺段间隔增厚的影像学鉴别诊断。方法收集2014年1月至2014年6月南京医科大学第一附属医院经手术及病理证实的78例肺腺癌患者的多层螺旋CT(MSCT)图像和MRI图像进行回顾性分析,总结毛刺和肺段间隔增厚的影像学区别。结果 MSCT图像中肺腺癌的毛刺征和肺段间隔增厚的出现率分别为32.1%和14.1%,前者显著高于后者(P<0.05)。MSCT图像中毛刺和增厚肺段间隔均表现为高密度线状影,T2-MRI中毛刺和增厚肺段间隔均表现为高信号线状影,动态增强磁共振(dynamic contrast enhanced magnetic resonance imaging,DCE-MRI)图像中毛刺可见,而增厚肺段间隔不可见。结论肺肿瘤毛刺和增厚的肺段间隔在MSCT和T2-MRI图像都表现为线状高密度影,但是毛刺的厚度不均一,而增厚的肺段间隔厚度均一,且连接肺段间静脉;DCE-MRI图像中仅可见毛刺征,DCE-MRI是鉴别毛刺征和肺段间隔增厚的有效手段。
Objective To determine the radiological difference between spiculation and thickened intersegmental septa in patients with pulmonary adenocarcinoma.Methods We retrospectively review the MSCT and MRI images from 78 patients with pulmonary adenocarcinoma.Imaging appearance of spiculation and thickened intersegmental septa were compared.Results Appearance rate of speculation is significantly higher than that of thickened intersegmental septa.Thickened intersegmental septa and spiculation were seen as lines of hyper-attenuation with or without linking to the intersegmental vein.Spiculation and thickened intersegmental septa could be seen on MSCT and T2-weighted MRI.Only spiculation could be seen on DCE-MRI.Conclusions Spiculation and thickened intersegmental septa could be distinguished through comparing their MSCT and MRI appearance.
