(C) CT perfusion with thresholded relative cerebral blood flow less than 30% that of normal tissue (magenta), suggesting a small region of irreversibly injured ischaemic core, and (D) time to maximum (Tmax) longer than 6 s (green), indicating tissue at risk of infarction in the absence ...
Therefore, demonstration of intraparenchymal or subarachnoid hemorrhage in small areas with flowsensitive MRI is extremely important in the diagnosis of CAA. At this point, it was requested to approach suspicious to the diagnosis of patients with transient focal neurological symptoms...
