Abstract
We used tagged MR imaging to investigate the flow in two lateral and two te rminal saccular intracranial aneurysm models of different neck sizes. Imagi ng was performed with a 1.5-T superconducting MR system using 2D fast spati al modulation of magnetization (SPAMM) sequences with an intersegmental del ay 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.
