We developed a novel three-dimensional (3D) image simulation system that is especially focused on pulmonary segmentectomy using new 3D computed tomography (CT) software. Based on contrast-enhanced high-resolution computed tomography (HRCT) images, the new software can quickly construct 3D pulmonary and bronchovascular images and generate a proposal for the appropriate segments to be resected. We performed the 3D image simulation and evaluated its accuracy in 20 patients for whom thoracoscopic segmentectomy was planned. We evaluated the anatomical validity comparing with HRCT findings and anatomical consistency with the operative findings on a three-point scale, respectively. The 3D image was evaluated as “good” for anatomical validity in 19 cases (95%) and for anatomical consistency with operative findings in 18 cases (90%). The novel 3D image simulation appeared to be easy to prepare, was anatomically reliable, and, therefore, was determined to be potentially useful.

我们开发了一种新型 3D (3D) 图像模拟系统，该系统特别专注于使用新的 3D 计算机断层扫描 (CT) 软件进行肺段切除术。基于对比增强的高分辨率计算机断层扫描 (HRCT) 图像，新软件可以快速构建 3D 肺和支气管血管图像，并为要切除的适当节段生成建议。我们对 20 名计划进行胸腔镜肺段切除术的患者进行了 3D 图像模拟并评估了其准确性。我们分别在三点量表上评估了与 HRCT 结果相比的解剖学有效性和与手术结果的解剖学一致性。19 例 (95%) 的解剖学有效性和 18 例 (90%) 的解剖学结果与手术结果的一致性被评估为 3D 图像“良好”。
