title: Seizures: a reaction to contrast media for computed tomography of the brain.
abstract: Seven patients had seizures in association with the use of intravenous contrast media for cranial computed tomography. Caution and close observation are indicated when contrast agents are administered to patients with suspected focal brain disorders that may lower the seizure threshold. Patients with tumors metastatic to the brain appear to be at specially increased risk.
