Discussion In the brain, abnormal contrast enhancement or opacification occurs by two
mechanisms: extravasation of contrast material from the intravasc;: ular space or a localized …

Thirty-six dogs were subdivided into five experimental groups and one control group for
assessing reactions to contrast media during ventriculography. The five contrast agents …

The cerebral ventricles of two neonates were demonstrated on CT scans and plain
radiographs after the intra-arterial injection of contrast material. Leakage of contrast material …

Ependymitis or ventriculitis, inflammation of the lining of CSF-filled ventricles, is a rare but
potentially serious complication of meningitis. If untreated, the destructive process …

Lesions of the ventricular ependyma and its derivatives can be visualized by CT scans, and
their nature and extent can be determined. Generalized enhancement of the ependyma …

Positive contrast media are still used in many countries for ventriculography as well as for
myelography. Numerous reports ofcomplications have, however, been published (adhesive …

From material of over 10,000 CTs a comparative study of computed tomography and
ventriculography with contrast media was carried out. We examined 18 patients with …

Pattern z. Diffuse increase in radionuc/ide activity throughout the brain mirrored a diffuse
encephalitis(Fig. i, 4-F). Nine patients had this pattern. Eight of these had diffuse …

Abnormal computed tomographic enhancement in the basal cisterns and cortical sulci was
observed in 21 of 42 patients after subarachnoid hemorrhage. The appearance is similar to …
