Three-dimensional (3D) CT with volume rendering and maximum intensity projection is an integral component of CT interpretation for diagnosis and treatment planning of vascular pathology. Cinematic rendering is a new rendering algorithm that incorporates a more advanced lighting model than that used for volume rendering, to create photorealistic 3D CT images. The post-processing tool is not yet widely available and its ultimate clinical utility has yet to be assessed in well-designed studies. Nonetheless, the striking level of detail and enhanced depiction of 3D anatomic relationships holds potential for improvements in diagnosis, interventional or operative planning and patient-centred care. In this pictorial essay, a series of complex cardiovascular cases are presented to demonstrate the enhanced display capabilities associated with cinematic rendering, and the utility to guide patient management and understanding is discussed.
具有容积再现和最大密度投影的三维（3D）CT是血管病变诊断和治疗规划中CT解读的一个组成部分。电影渲染是一种新的渲染算法，它采用了比容积再现更先进的光照模型，以创建逼真的3D CT图像。这种后处理工具尚未广泛应用，其最终临床效用尚未在精心设计的研究中得到评估。尽管如此，其惊人的细节水平和对3D解剖关系的增强描绘在改善诊断、介入或手术规划以及以患者为中心的护理方面具有潜力。在这篇图文并茂的文章中，展示了一系列复杂的心血管病例，以证明与电影渲染相关的增强显示能力，并讨论了其在指导患者管理和理解方面的效用。
