多层螺旋CT二维(2D)及三维(MPR)在周围型肺癌的临床应用

目的　探讨多层螺旋CT二维 (2D)和多平面重建技术 (MPR)在周围型肺癌的临床应用价值。方法　 17例周围型肺癌行多层螺旋CT扫描 (层厚 1～ 2mm)和多平面重建。结果　 2D图可显示周围型肺癌内部结构、分叶征、毛刺征、病灶周围血管、胸膜、纵隔结构的关系 ,但显示的范围、征象较局限。MPR可以多个方面显示肿块与胸膜、纵隔结构关系 ,MPR可多方面清楚显示肺癌本身征象和肺癌与周围组织的关系。结论　以 2D螺旋CT图为基础 ,结合MPR对诊断周围型肺癌有重要的临床应用价值

Clinical Application of Two Dimensions Reconstruction and Multiple Planes Reconstruction(MPR) Technique with Multiple Slices Spiral CT in Diagnosis for Peripheral Pulmonary Carcinoma

Objective To evaluate the clinical application of two dimensions reconstruction(TDR) and multiple planes reconstruction(MPR) technique with multiple slices spiral CT in diagnosis for peripheral pulmonary carcinoma(PPC).Methods 17 cases of peripheral pulmonary carcinoma were examined with the multiple slices spiral CT scan and MPR.Results The imaging of TDR revealed the internal structure ,burr sign and petaline sign of PPC and the surrounding vessels of focus. It also showed the spatial structure between focus and pleural , mediastine. But the area and the features of the imaging of TDR were limited. The MPR could reveal the spatial structure between focus and pleural , mediastine in many aspects .It also revealed the features of pulmonary carcinoma and the spatial structure between focus and surrounding tissue.Conclusion It is valuable for diagnosis of peripheral pulmonary carcinoma that application of MPR based on the imaging of two dimensions reconstruction.
