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.
