We aimed to develop an intuitive, interactive, three-dimensional (3D) MRI modelling technique to produce a 3D image of fistula-in-ano.
The 3D model was created from standard two-dimensional (2D) MRI sequences to produce an image that is anatomically correct. Individual muscle and soft-tissue layers were extracted from T1-weighted sequences and fistula pathology from short TI inversion recovery (STIR) sequences, to produce two separate volumes. These were then fused using postprocessing software (Vitrea Workstation version 6.3) to generate a 3D model.
The final 3D model was incorporated into a PDF file that has an integrated computer aided design (CAD) viewer, allowing the surgeon to rotate it in any direction during preoperative planning or whilst in theatre.
As an adjunct to 2D MRI images and the associated radiology report, this model communicates the fistula anatomy to the clinician more clearly and should be particularly useful in complex cases.
我们旨在开发一种直观、互动的三维（3D）MRI 建模技术，以生成肛门瘘的 3D 图像。
从标准二维（2D）MRI 序列创建 3D 模型，以生成解剖正确的图像。从 T1 加权序列中提取单个肌肉和软组织层，并从短 TI 反转恢复（STIR）序列中提取瘘管病理学，以生成两个单独的体积。然后使用后处理软件（Vitrea Workstation 版本 6.3）融合这些体积，以生成 3D 模型。
最终的 3D 模型被合并到一个 PDF 文件中，该文件具有集成的计算机辅助设计（CAD）查看器，允许外科医生在术前规划或手术期间以任何方向旋转它。
作为 2D MRI 图像和相关放射学报告的辅助手段，该模型更清晰地向临床医生传达了瘘管解剖结构，在复杂情况下应该特别有用。
