A gold standard of cerebral vessel imaging remains the digital subtraction angiography (DSA) performed in three projections. However, in specific clinical cases, many additional projections are required, or a complete visualization of a lesion may even be impossible with 2D angiography. Three-dimensional (3D) reconstructions of rotational angiography were reported to improve the performance of DSA significantly. In this pictorial essay, specific applications of this technique are presented in the management of intracranial aneurysms, including: preoperative aneurysm evaluation, intraoperative imaging, and follow-up. Volumetric reconstructions of 3D DSA are a valuable tool for cerebral vessels imaging. They play a vital role in the assessment of intracranial aneurysms, especially in evaluation of the aneurysm neck and the aneurysm recanalization.
脑血管成像的金标准仍然是在三个投影方向上进行的数字减影血管造影（DSA）。然而，在特定临床病例中，需要许多额外的投影方向，甚至二维血管造影可能无法完整显示病变。据报道，旋转血管造影的三维（3D）重建可显著提高DSA的性能。在这篇图文并茂的文章中，介绍了该技术在颅内动脉瘤治疗中的具体应用，包括：术前动脉瘤评估、术中成像和随访。三维DSA的容积重建是脑血管成像的一种有价值的工具。它们在颅内动脉瘤的评估中起着至关重要的作用，尤其是在评估动脉瘤颈部和动脉瘤再通方面。
