目的评价周围型肺癌胸膜凹陷征表面遮盖成像(SSD)的三维肺表面表现。资料与方法比较30例周围型肺癌SSD及轴位图像的完整胸膜凹陷显示率,其中8例术后行充气标本制作和/或有肺叶术中充气照片。结果21例表现为三维完整凹陷征(70%),10例表现为轴位完整凹陷征(33.33%),SSD对完整胸膜凹陷征显示率高于横断位(P<0.05)。8例有肺癌肺叶照片的患者中,4例表现为三维完整凹陷征,4例表现为三维非完整凹陷征。结论与薄层轴位图像相比,SSD显示出胸膜凹陷征更佳。 Objective To evaluate the three-dimensional (3D) pulmonary surface manifestations of surface-covered images (SSDs) of pleural indentations in peripheral lung cancer. Materials and Methods 30 cases of peripheral lung cancer SSD and axial images of the complete pleural indentation display rate, of which 8 cases were inflated specimens and / or lobectomy inflatable photos. Results 21 cases showed three-dimensional intact sag (70%) and 10 cases showed complete sagittal axial sign (33.33%). SSD showed a higher rate of complete pleural indentation than transverse sag (P <0.05). Of the 8 patients with lung cancer lung photographs, 4 showed complete three-dimensional sag and 4 showed incomplete three-dimensional sag. Conclusions SSD shows better pleural indentation than thin-layer axial images.
