Encephalopathy has been documented after administration of iopromide, (9,10) iohexol, (11) ioxilan, (4) and metrizamide
. The mechanism of neurotoxicity is unclear, but several theories have been formulated.
In 1974, this procedure was transformed with metrizamide
and years later with iohexol, both nonionic contrast agents .
Suspensions of liberated HSCs were prepared by centrifugation on a double-layered (17%/11.5%) metrizamide
solution (Sigma, St.

(16-18) Iohexol is reported to be safer than metrizamide
and iopamidol for equine and canine myelography.
The partially dissociated cells were then added to Lebowitz-15 (L-15; Gibco, Grand Island, NY), defined serum-free medium and further dissociated by running the mixture through a 1 ml pipette, followed by centrifugation (400 x g for 15 min; Beckman Centrifuge) over a layer of 6.8% metrizamide
