Imaging Data
于手术室的MRI单元紧急行脑MRI评估
Urgent brain MRI in the intraoperative MRI Suite
△T1WI和T2WI：幕上脑积水，脑沟、脑池蛛网膜下腔呈等T1和等-高T2信号
△T1WI and T2WI showed a supratentorial hydrocephalus, and that the subarachnoid space of cerebral sulci and cistern spansented with an iso-intense sigal on T1WI and an iso-intense or slightly hyper-intense signal on T2WI
△头颅3D-TOF-MRA：颅内动脉显影极差（提示血流速度缓慢），双侧颞浅动脉显影正常（橙箭）
△Cranial 3D-TOF-MRA: the blood signal of all intracranial arteries was very poor (the blood flow rate was very slow) ; but the blood signal of bilateral superficial temporal arteries was normal (orange arrow)
△SWI：广泛的脑沟和脑表面显著低信号（提示出血）
△SWI: significant low signal in the brain sulci and surface of bilateral cerebellar and hemispheres prompting subarachnoid hemorrhage
脑CT评估
Brain CT assessment
△头颅CT：幕上脑积水，严重蛛网膜下腔出血
△Cranial CT revealed a supratentorial hydrocephalus and a large amount of subarachnoid hemorrhage
