Introduction

Stroke remains a leading cause of mortality and permanent disability worldwide.[1] Brain imaging plays a crucial role in early diagnosis and yields essential information regarding tissue integrity, a factor that is determinant in identifying patients likely to benefit from thrombolytic therapy. Readily available in most settings, computed tomography (CT) maintains a dominant role in the evaluation of patients with acute stroke. In this paper, we discuss several innovations in perfusion and CT angiography of acute stroke, which have an impact on quality, consistency, and radiation dose.
