title: Low dose arterial contrast enhancement for cranial computed tomography in renal insufficiency.
abstract: In patients with severe renal insufficiency, the high iodine doses used for intravenous contrast medium enhanced CT can lead to renal injury. To minimize renal toxicity in one such patient, dynamic contrast enhanced CT was performed during right common carotid arterial infusion of 17 ml of 30% diatrizoate meglumine solution. Intense homogeneous contrast enhancement of an otherwise isodense mass permitted a diagnosis of meningioma, with excellent definition of tumor extent.
