Surface rendering of diagnostic imaging data can reveal hidden conditions with an almost life-like realism. However, early gestation images alone are often insufficient to accurately predict postnatal anatomy. Yet, time-sensitive decisions may have to be made before detailed imaging becomes possible. In this case series, we evaluate how combining medical illustration with cross-sectional diagnostic imaging can enhance the accuracy and clinical value of early visualization of conjoined twins.
Early gestation magnetic resonance imaging scans underwent semiautomated computerized post hoc manipulation to allow the medical illustrator to create the most effective images of the twins.
Four sets of conjoined twins were diagnosed before 17 weeks. Surface modeling allowed spatial manipulation of the twins to highlight their anatomic connections. Further volumetric enhancement and critical interpretation of the models assisted the illustrator in creating life-like, accurate images of the twins. These illustrations allowed parents to visualize the likely presentation at birth and helped the multidisciplinary team to plan postnatal management.
Surface rendering and surface modeling can be combined with medical illustration to create realistic, informative images of developing fetuses, using a level of detail that is tailored to the intended audience. This may be particularly useful in visualizing complex anomalies like conjoined twins.
诊断成像数据的表面渲染能够以近乎逼真的效果揭示隐藏的病症。然而，仅靠孕早期图像往往不足以准确预测产后解剖结构。然而，在能够进行详细成像之前，可能不得不做出对时间敏感的决策。在本病例系列中，我们评估了将医学插图与横断面诊断成像相结合如何提高联体双胎早期可视化的准确性和临床价值。
对孕早期磁共振成像扫描进行半自动计算机化事后处理，以便医学插图画家创建最有效的双胎图像。
在17周前诊断出4对联体双胎。表面建模允许对双胎进行空间操作，以突出它们的解剖连接。对模型的进一步体积增强和关键解读帮助插图画家创建出逼真、准确的双胎图像。这些插图使父母能够直观了解出生时可能的情况，并帮助多学科团队规划产后管理。
表面渲染和表面建模可以与医学插图相结合，利用适合目标受众的细节水平，创建发育中胎儿的逼真、信息丰富的图像。这在可视化联体双胎等复杂畸形时可能特别有用。
