Estimation of fusiform intracranial aneurysm growth by serial magnetic resonance imaging.

Purpose: Intracranial aneurysm (IA) growth is associated with increased morbidity. We sought to establish a quantitative computational method based on contrast-enhanced MR angiography (CE-MRA) for estimating aneurysmal volume changes over time.

Materials And Methods: Computational volume calculations were tested against a distensible phantom.
