描述了一种通用方法，用于验证 2D 数字减影血管造影 (DSA) 的 3D 成像模式，以进行脑动静脉畸形 (BAVM) 描绘。它依赖于对 3D 放射外科目标与其 2D 描绘的统计兼容性的评估。该方法通过 3D 旋转血管造影 (3DRA) 的初步评估得到证实。一般来说，BAVM 勾画不能单独在 3DRA 上进行。然而，在我们的研究中，对于相当简单的病例，3DRA 显示出与 DSA 相似的性能，对于三名患者甚至更好。相反，确定并讨论了三个有问题的案例。 (C) 2008 Elsevier Ltd. 保留所有权利。
A general methodology is described to validate a 3D imaging modality with respect to 2D digital subtracted angiography (DSA) for brain AVMs (BAVM) delineation. It relies on the assessment of the statistical compatibility of the radiosurgical target delineated in 3D with its delineations in 2D. This methodology is demonstrated through a preliminary evaluation of 3D rotational angiography (3DRA). Generally speaking, BAVM delineation cannot be performed on 3DRA alone. However, in our study, 3DRA showed similar performances to DSA for rather easy cases, and even better for three patients. Conversely, three problematic cases are identified and discussed.
