title: Absence of cerebrospinal fluid abnormalities and spinal cord lesions after iotrolan cervical myelography in normal cats: an open placebo-controlled study.
abstract: Iotrolan (Isovist 300, Schering AG) at a volume of 0.5 ml/kg B.W. was injected into the cerebellomedullary cistern of 12 cats (Isovist group); the same volume of normal saline was injected in four other cats (control group). Two ml of CSF was collected from each anaesthetized cat by cisternal tap immediately before, and 7 and 15 days after, injection. The physical characteristics, specific gravity, total cell count and total protein concentration of each CSF sample were recorded. The cats were euthanized on day 15 immediately after CSF samples and spinal cord specimens had been obtained. Spinal cord histopathology was examined with the aid of light and transmission electron microscopy. The physical characteristics of all the CSF samples were within the reference range. No significant differences were found for CSF specific gravity, total cell count and total protein concentration between the pre-injection samples and those collected 7 and 15 days post-injection in both groups; no spinal cord lesions were detected in histopathology.
