In order to examine clinical usefulness of three-dimensional (3D) imaging of solitary pulmonary nodules froms serial thin-section CT images, 3D reconstruction of a small peripheral lung adenocarcinoma was performed using the inflated fixed lung specimen resected surgically. The left upper lobe was fixed and air-dried by Heitzman's method, and was scanned contiguously 20 times at a section thickness of 2 mm and a section interval of 2 mm. Bronchi, pulmonary vessels and the tumor presented on the CT images were input to a 3D reconstruction personal computer system, and then 3D images were obtained. The reconstructed 3D images included various tomographic images of bronchi and pulmonary vessels. It is expected that this method would be one of the most useful imaging techniques for the differential diagnosis of solitary pulmonary nodules.
为了通过连续薄层CT图像研究孤立性肺结节三维（3D）成像的临床实用性，使用手术切除的充气固定肺标本对1例小的周围型肺腺癌进行了三维重建。左肺上叶采用海茨曼法固定并风干，以2mm的层厚和2mm的层间距连续扫描20次。将CT图像上显示的支气管、肺血管和肿瘤输入到三维重建个人计算机系统，然后获得三维图像。重建的三维图像包括支气管和肺血管的各种断层图像。预计该方法将成为孤立性肺结节鉴别诊断最有用的成像技术之一。
