Abstract: ColorViz is a cerebrovascular imaging technique with time resolution that integrates vascular information from three phases of multi-phase CT angiography (mCTA) into a single time-varying color coded images. By analyzing the image, it evaluates the cerebral collateral circulation and predict the outcomes of patients with ischemic stroke. ColorViz can shorten the evaluation time of collateral circulation and improve the objectivity of evaluation. Moreover, its evaluation of collateral circulation status is closely associated with the evaluation of collateral circulation status of mCTA, digital subtraction angiography, and CT perfusion imaging. This article reviews the application of ColorViz in evaluating collateral circulation in patients with acute ischemic stroke.
