A review on imaging techniques and quantitative measurements for dynamic imaging of cerebral aneurysm pulsations

Abstract Measurement of intracranial aneurysm wall motion may refine the current rupture risk estimation. A golden standard for measuring aneurysm pulsation is lacking. The aim is to evaluate magnitudes of aneurysm pulsation as published in current literature. Embase and PubMed were searched for pub...
