Our aim was to demonstrate the orifice of intracranial aneurysms by magnetic resonance angiography (MRA). The aneurysmal orifice is that part of its lumen that communicates with the parent vessel. We studied 12 patients with 17 intracranial aneurysms using three-dimensional display (3DD) MRA; 15 of the aneurysms had previously been shown by digital subtraction angiography (DSA). The overall image quality of 3DD MRA was excellent in 10 patients. The orifice was clearly demonstrated in 13 aneurysms (76%) providing unique information about its size, shape and orientation. The orifice of 2 aneurysms (12%) was not demonstrated. Two aneurysms (12%) were not detected on MRA. Although 3DD MRA has limitations, this study suggests that it can accurately define the orifice of aneurysms and could be used to provide information crucial for endovascular treatment.
我们的目的是通过磁共振血管造影（MRA）显示颅内动脉瘤的开口。动脉瘤开口是其管腔与母血管相通的部分。我们使用三维显示（3DD）MRA对12例患有17个颅内动脉瘤的患者进行了研究；其中15个动脉瘤先前已通过数字减影血管造影（DSA）显示。10例患者的3DD MRA整体图像质量极佳。13个动脉瘤（76%）的开口得到清晰显示，提供了有关其大小、形状和方向的独特信息。2个动脉瘤（12%）的开口未显示。MRA未检测到2个动脉瘤（12%）。尽管3DD MRA存在局限性，但本研究表明它可以准确界定动脉瘤的开口，并可用于提供对血管内治疗至关重要的信息。
