The aim of this study was to evaluate the contrast enhancement, pharmacokinetics, dialyzability, and safety of gadodiamide in patients on hemodialysis.


Thirteen hemodialysis patients with abdominal disease were examined after receiving intravenous gadodiamide (0.1 mmol/kg body weight) by magnetic resonance imaging (MRI) and were dialyzed at l, 3, 5, and 8 days. Blood samples were obtained immediately before, during, and at the end of the first hemodialysis session and immediately before and at the end of the next three sessions. The complete blood count, blood biochemistry, beta2-microglobulin, and gadolinium were measured. Dialysis of urea, creatinine, and gadolinium during the first hemodialysis session was assessed. Precontrast and postcontrast MRI and Gd-enhanced MR angiography (MRA) images were reviewed and visually evaluated by two radiologists; their evaluation was based on consensus.


Gadodiamide did not cause any changes in renal function. An average of 73.8%, 92.4%, and 98.9% of the gadodiamide dose was eliminated by the end of the first, second, and third hemodialysis sessions, respectively. The average half-time of gadodiamide was 1.93 h (SD 0.55). The mean clearance of gadodiamide during hemodialysis was 63.5 ml/min (SD 21.9). There were no side effects related to the injection of gadodiamide. In all cases, diagnosable MRI and MRA images were obtained after gadodiamide injection in the hemodialysis patients.


In hemodialysis patients, gadodiamide achieves diagnosable images. It is dialyzable and can be used safely without measures to increase excretion.
