title: Comparative efficacy of contrast agents in computed tomography scanning of the brain.
abstract: Various contrast agents with either sodium or meglumine cations and iothalamate and diatrizoate anions are compared in a series of patients with malignant gliomas. There is no difference in the ability of these agents to enhance tumors in cranial computed tomography.
