Urographic excretion studies with metrizamide and "Dimer": a high dose comparison in dogs.

Metrizamide, a new non-ionic, triodinated contrast agent has been considerable for intravenous urography. Theory predicts that lower osmotic diuresis with this agent should lead to higher urinary iodine concentrations than with ionic agents, at equivalent iodine doses. However, a distinct advantage with metrizamide has not been observed with doses of 175… (More)
