Résumé
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.
