This article explores the use of multiphase CT angiography (CTA) as a valuable tool in acute stroke management. Unlike traditional imaging methods, multiphase CTA provides a more comprehensive view of the neurovascular system and can detect occlusions and aid in treatment decision-making. Recent studies have shown that multiphase CTA has high accuracy in identifying patients who are suitable for endovascular treatment. Furthermore, it has also been used to visualize intracranial aneurysms and track the development of collateral circulation during and after treatment. Despite concerns regarding radiation exposure and image interpretation, multiphase CTA remains an essential imaging modality in the management of acute stroke patients.
