Gadodiamide is a gadolinium based contrast agent used in MR imaging procedures to assist in the visualization of blood vessels. It is commonly marketed under the trade name Omniscan.


Gadodiamide is used to visualize blood vessels during MRI procedures. The use of gadodiamide in these scans allows for the diagnosis of intracranial lesions or blood-brain barrier anomalies.[1] It is a high osmolarity contrast agent at 789 mOsmol per kg of water.

Gadolinium based agents may cause a toxic reaction known as NSF in patients with severe kidney problems.
