The penetration of metrizamide into the brain after routine lumbar myelography as shown by cerebral computed tomography and its effect on auditory brainstem transmission time.

Metrizamide is a widely used contrast medium with some well known adverse reactions. In a preliminary study, CT scans and brain stem evoked potentials (BAEP) were done before and 18 hours following lumbar myelography on 12 patients. A statistically significant prolongation of the BAEP was observed. Metrizamide therefore seems to be a potent substance in clinical use as indicated by its effect on BAEP. BAEP should not be done within the first few days after myelography with metrizamide.

Prognostic significance of cerebral computed tomography results in supratentorial infarction.

In 69 patients with supratentorial cerebral infarction findings at computed tomography (CT) were related to clinical state on admission and course of recovery. In patients with initial disability of slight to moderate degree CT did not provide prognostically useful information; in patients with severe symptoms at onset location of lesion to the internal capsule or the right parietal lobe and the presence of the mass effect, as single factors or in combination, were ominous CT indicators in terms of functional recovery.

Computed tomography and subarachnoid hemorrhage.

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. Among the other 14 there were three in whom no aneurysm was found on angiography. The distribution of blood in those that showed it was useful in pointing to the position of the aneurysm. Much other information was obtained, for instance about rebleeding and infarction. CT should routinely be the primary examination, followed by selective angiography.
