Clinical Application of Two Dimensions Reconstruction and Surface Shaded Display (SSD) with Multiple Slices Spiral CT in Diagnosis of Peripheral Pulmonary Carcinoma / 实用放射学杂志

ABSTRACT

Objective To assess the value of the clinical application of two dimensions reconstruction and surface shaded display (SSD) with multiple slices spiral CT in diagnosis of peripheral pulmonary carcinoma .Methods Peripheral pulmonary carcinomas in 35 cases were scanned by multiple slices spiral CT. The source images of CT were reconstructed by two dimensions reconstruction and surface shaded display (SSD) techniques.Results The images of two dimensions reconstruction could show the internal structure of lesions,lobulated sign burr sign,the vessels surrounding the focus,and the relation between focus and pleural as well as mediastina,but the relation of tumor and the organs surrounding the tumor could be showed not stereoscopically and directly.The images of SSD could not only reveal the relation between focus and surrounding organs in different dirctions but also revealed the features of pulmonary carcinoma stereoscopically and directly.Conclusion It is valuable for diagnosis of peripheral pulmonary carcinoma that application of SSD based on the images of two dimensions reconstruction.
