Hyperdense basilar artery sign on unenhanced CT predicts thrombus and outcome in acute posterior circulation stroke.


BACKGROUND AND PURPOSE In acute stroke patients, the presence of a hyperdense middle cerebral artery sign on unenhanced CT is a specific but insensitive indicator of acute thrombosis. Our purpose was to determine whether the hyperdense basilar artery (HDBA) sign has utility in detecting thrombosis and predicting outcome in patients presenting with signs and… (More)
