Improved visualization of medium vessel occlusion stroke with time-variant color-coded multiphase CT angiography maps: A technical note

Abstract

Abstract Detecting medium vessel occlusions (MeVOs) is often challenging due to their distal location and small vessel size. Herein we describe an innovative imaging technique for fast and reliable MeVO detection: time-variant color-coded multiphase CTA. Three CTA phases of the intracranial vasculature are color-coded and displayed in a single summation image, which improves visualization of MeVOs through a color indicator effect, thereby substantially facilitating MeVO detection, particularly for readers with limited experience.
