Neuroradiology
-
CT scans have been made on 39 of 41 patients who presented with subarachnoid hemorrhage. Blood could be visualized in the cisterns of 18 of 32 examinations performed within five days of the hemorrhage all having aneurysms. ⋯ Much other information was obtained, for instance about rebleeding and infarction. CT should routinely be the primary examination, followed by selective angiography.
