  • Title: The use of cerebral ventriculography for verification of intracerebroventricular cannula placement in the live rat.
    Author: Gwosdow AR, Besch EL, Poulos PW, Ganey T.
    Journal: Lab Anim Sci; 1985 Apr; 35(2):176-7. PubMed ID: 3873576.
    Abstract:
    A technique using cerebral ventriculography for verification of intracerebroventricular cannula placement in the live rat is described. A radiopaque contrast medium, diatrizoate meglumine, was injected into the right lateral ventricle through a cannula stereotaxically implanted into the brain. Radiographic visualization of the radiopaque contrast material in the lateral ventricle and the subarachnoid space verified cannula placement. Transient muscular spasms were observed in about 38% of the injected rats but no lasting changes were observed in the behavior or appearance of these rats.
