Collateral circulation is a potent predictor of revascularization and clinical outcomes after acute ischemic stroke, and various features of collateral flow may be seen with a variety of neuroimaging techniques. Maas et al. investigated assessment of collaterals on CT angiography source images as a predictive tool in ischemic stroke.
