Gadopentetate dimeglumine as an alternative contrast material for use in angiography

Gadopentetate dimeglumine, gadolinium chelated by DTPA, has been used safely as a contrast material in MR imaging [1]. High attenuation of X-rays by gadopentetate dimeglumine (0.5 mmollml, Magnevist, Schening, Berlin, Germany) administered IV in preparation for MR imaging has been reported on CT scans in laboratory studies and on radiographs of the kidneys [2]. We report a case in which a patient who had a ruptured hepatocellular carcinoma and a history of hypersensitivity to nonionic iodinated contrast media was treated with emergency transcatheter arterial embolization. Gadopentetate dimeglumine was used as a contrast material for digital subtraction angiography.
