Gadodiamide-based coronary angiography in a patient with severe renal insufficiency.

The risk of contrast-induced nephropathy (CIN) is extremely high in patients with preexisting renal insufficiency. Gadolinium-based coronary angiography has been proposed as an approach to prevent CIN in this high risk subgroup. We report the use of gadodiamide-based coronary angiography in a patient with severe renal insufficiency and in vitro comparisons of combinations of iodinated contrast with gadodiamide and saline.
