Patient-specific 3D modeling is the first step towards image-guided surgery, the actual revolution in surgical care. Pediatric and adolescent patients with rare tumors and malformations should highly benefit from these latest technological innovations, allowing personalized tailored surgery. This study focused on the pelvic region, located at the crossroads of the urinary, digestive, and genital channels with important vascular and nervous structures. The aim of this study was to evaluate the performances of different software tools to obtain patient-specific 3D models, through segmentation of magnetic resonance images (MRI), the reference for pediatric pelvis examination. Twelve software tools freely available on the Internet and two commercial software tools were evaluated using T2-w MRI and diffusion-weighted MRI images. The software tools were rated according to eight criteria, evaluated by three different users: automatization degree, segmentation time, usability, 3D visualization, presence of image registration tools, tractography tools, supported OS, and potential extension (i.e., plugins). A ranking of software tools for 3D modeling of MRI medical images, according to the set of predefined criteria, was given. This ranking allowed us to elaborate guidelines for the choice of software tools for pelvic surgical planning in pediatric patients. The best-ranked software tools were Myrian Studio, ITK-SNAP, and 3D Slicer, the latter being especially appropriate if nerve fibers should be included in the 3D patient model. To conclude, this study proposed a comprehensive review of software tools for 3D modeling of the pelvis according to a set of eight criteria and delivered specific conclusions for pediatric and adolescent patients that can be directly applied to clinical practice.
患者特定的 3D 建模是图像引导手术的第一步，这是手术护理的真正革命。患有罕见肿瘤和畸形的儿科和青少年患者将从这些最新的技术创新中受益匪浅，这些创新允许进行个性化定制手术。本研究集中在骨盆区域，该区域位于泌尿、消化和生殖通道的交汇处，有重要的血管和神经结构。本研究的目的是评估不同软件工具通过对磁共振成像 (MRI) 的分割来获得患者特定的 3D 模型的性能，MRI 是小儿骨盆检查的参考。评估了 12 种免费的互联网上的软件工具和 2 种商业软件工具，使用 T2-w MRI 和弥散加权 MRI 图像。根据三个不同用户评估的 8 个标准对软件工具进行评分：自动化程度、分割时间、可用性、3D 可视化、是否存在图像配准工具、示踪工具、支持的操作系统以及潜在的扩展（即插件）。根据一组预定义的标准，对 MRI 医学图像的 3D 建模软件工具进行了排名。该排名使我们能够制定用于小儿患者骨盆手术计划的软件工具选择指南。排名最高的软件工具是 Myrian Studio、ITK-SNAP 和 3D Slicer，如果要将神经纤维包含在 3D 患者模型中，则后者特别合适。总之，本研究根据一组 8 个标准对骨盆的 3D 建模软件工具进行了全面评估，并为儿科和青少年患者提供了具体的结论，这些结论可以直接应用于临床实践。
