Planning for surgical intervention for patients with complex congenital heart disease requires a comprehensive understanding of the individual's anatomy. Cinematic rendering (CR) is a novel technique that purportedly builds on traditional volume rendering (VR) by converting CT image data into clearly defined 3D reconstructions through the stimulation and propagation of light rays. The purpose of this study was to compare CR to VR for the understanding of critical anatomy in unoperated complex congenital heart disease.
In this retrospective study, CT data sets from 20 sequential scanned cases of unoperated paediatric patients with complex congenital heart disease were included. 3D images were produced at standardised and selected orientations, matched for both VR and CR. The images were then independently reviewed by two cardiologists, two radiologists and two surgeons for overall image quality, depth perception and the visualisation of surgically relevant anatomy, the coronary arteries and the pulmonary veins.
Cinematic rendering demonstrated significantly superior image quality, depth perception and visualisation of surgically relevant anatomy than VR.
Cinematic rendering is a novel 3D CT-rendering technique that may surpass the traditionally used volumetric rendering technique in the provision of actionable pre-operative anatomical detail for complex congenital heart disease.
为患有复杂先天性心脏病的患者规划手术干预需要全面了解其解剖结构。电影渲染（CR）是一种新颖的技术，据称通过刺激和传播光线将 CT 图像数据转换为清晰定义的 3D 重建，从而建立在传统的体积渲染（VR）之上。本研究旨在比较 CR 与 VR 对未手术治疗的复杂先天性心脏病关键解剖结构的理解。
在这项回顾性研究中，纳入了 20 例连续扫描的未经手术治疗的儿科复杂先天性心脏病患者的 CT 数据集。以标准和选定的方向生成 3D 图像，与 VR 和 CR 匹配。然后，两名心脏病专家、两名放射科医生和两名外科医生独立对整体图像质量、深度感知以及手术相关解剖结构（冠状动脉和肺静脉）的可视化进行评估。
与 VR 相比，电影渲染在图像质量、深度感知和手术相关解剖结构的可视化方面表现出显著优势。
电影渲染是一种新颖的 3D CT 渲染技术，在为复杂先天性心脏病提供可操作的术前解剖细节方面可能优于传统的容积渲染技术。
