Quantifying unruptured giant intracranial aneurysms by measuring diameter and volume-a comparative analysis of 69 cases

摘要

Intracranial aneurysms (IA) are usually quantified according to their largest diameter. However, volumetry has recently been increasingly conducted as well, especially in giant intracranial aneurysms (GIAs). Since so far the true value of GIA volumetry is unknown, we designed a trial to examine correlations between GIA diameter and volume with special focus on clinical implications.
