The feasibility of rendering three dimensional (3D) pelvic models of vaginal, urethral and paraurethral lesions from 2D MRI has been demonstrated previously. To quantitatively compare 3D models using two different image processing applications: 3D Slicer and OsiriX. Secondary analysis and processing of five MRI scan based image sets from female patients aged 29-43 years old with vaginal or paraurethral lesions. Cross sectional image sets were used to create 3D models of the pelvic structures with 3D Slicer and OsiriX image processing applications. The linear dimensions of the models created using the two different methods were compared using Bland-Altman plots. The comparisons demonstrated good agreement between measurements from the two applications. The two data sets obtained from different image processing methods demonstrated good agreement. Both 3D Slicer and OsiriX can be used interchangeably and produce almost similar results. The clinical role of this investigation modality remains to be further evaluated.
先前已证明从二维磁共振成像（MRI）生成阴道、尿道及尿道旁病变的三维（3D）盆腔模型的可行性。为使用两种不同的图像处理应用程序（3D Slicer和OsiriX）对3D模型进行定量比较。对5例年龄在29 - 43岁患有阴道或尿道旁病变的女性患者基于MRI扫描的图像集进行二次分析和处理。使用3D Slicer和OsiriX图像处理应用程序，利用横断面图像集创建盆腔结构的3D模型。使用布兰德-奥特曼图比较两种不同方法创建的模型的线性尺寸。比较结果表明两种应用程序的测量结果具有良好的一致性。从不同图像处理方法获得的两组数据集显示出良好的一致性。3D Slicer和OsiriX均可互换使用并产生几乎相似的结果。这种检查方式的临床作用仍有待进一步评估。
