title: Comparison of metrizamide CT cisternography with radionuclide cisternography in abnormal cerebrospinal fluid dynamics.
abstract: Metrizamide CT cisternograms were performed on 39 patients with a clinical diagnosis of CSF abnormalities; 20 of these patients underwent radionuclide cisternography as well. Comparison of metrizamide CT and RN cisternography revealed good correlation in the degree, extent, and time sequence of ventricular reflux as well as the extent of cortical staining and cisternal filling. Metrizamide cisternography had the advantage of excellent anatomic detail and lower exposure dose, although minor complications were more frequent with this technique. Metrizamide CT cisternography has a potential to become the preferred method of evaluating patients with abnormal CSF dynamics.
