title: Computed tomography in the evaluation of intracranial aneurysms and subarachnoid hemorrhage.
abstract: Computed tomography (CT) is a reliable technique for examining patients with subarachnoid hemorrhage and intracranial aneurysms. Extravasated blood is easily recognized and the location of the ruptured aneurysm may frequently be predicted by its distribution into the subarachnoid spaces and brain parenchyma. CT alleviates the need for repeat angiography while following the patient's clinical evolution since it clearly shows rebleed, edema follwoing vasospasm, and hydrocephalus.
