我们使用标记磁共振成像来研究不同瘤颈大小的双侧和两端囊状颅内动脉瘤模型中的血流。成像采用1.5 T超导MR系统，采用2D快速空间磁化调制（SPAMM）序列，节段间延迟为25毫秒。囊状动脉瘤模型中的血流随瘤颈的形状和大小而变化：宽颈动脉瘤的血流速度比窄颈动脉瘤快。
We used tagged MR imaging to investigate the flow in two lateral and two terminal saccular intracranial aneurysm models of different neck sizes. Imaging was performed with a 1.5-T superconducting MR system using 2D fast spatial modulation of magnetization (SPAMM) sequences with an intersegmental delay of 25 milliseconds. The flow in the saccular aneurysm models varied with the shape and size of the neck: flow was faster in wider-necked aneurysms than in those with narrower necks.
