Intracranial Iotrolan Distribution following Cervical Myelography

Following iotrolan cervical myelography 14 consecutive patients were evaluated with respect to intracranial contrast distribution and elimination, side effects, EEG-changes and psychometric assessments. The contrast medium is distributed in the subarachnoid space, in the ventricles and finally extracellularly in the cortex. Headache was the most prevalent side effect, occurring in half of the patients, 43% of “severe” grade. Eight patients showed mild nonspecific EEG-changes and all patients showed neuropsychologic disturbances.
