BRUSH Sign: Radiolographic Marker of Cerebral Infarctus Prognosis

Today the treatment of ischemic stroke in acute phase is based on medicinal or endovascular revascularization. Cerebral MRI sequences help the diagnostic. This procedure uses deoxyhemoglobin as an endogenous tracer. This is also a scorer of cerebral ischemia and the increase lets visualized transcerebral veins in the suffering zone giving a brush aspect. Several studies show the interest of this sign and conclude that deoxyhemoglobin presence is a predictive factor of cerebral ischemia. The aim of the study is to evaluate this brush-sign and correlate it with the prognosis retrospectively.
