Iopamidol (INN), sold under the brand name Isovue among others, is a nonionic, low-osmolar iodinated contrast agent, developed by Bracco Diagnostics.

[5] It is also indicated for intrathecal administration in adult neuroradiology including myelography (lumbar, thoracic, cervical, total columnar), and for contrast enhancement of computed tomographic (CECT) cisternography and ventriculography.

[4] As with other iodinated contrast agents there are concerns regarding safety, particularly relating to effects on renal function and allergic type reaction.

Early generations of intravenous (IV) contrast carried considerable nephrotoxicity, necessitating continual assessment of renal function.

IV and PO (per os, by mouth) fluids are encouraged post operation to facilitate excretion of contrast.
