Innovations in CT imaging of acute stroke: Adding value, reducing dose, improving consistency, by Anne Marie McLellan, DO, Idoia Corcuera-Solano, MD, and Lawrence N. Tanenbaum, MD, FACR.

Stroke remains a leading cause of mortality and permanent disability worldwide. 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 per- fusion and CT angiography of acute stroke, which have an impact on quality, consistency, and radiation dose.
