Abstract

A method of preparing a BaSO4 contrast agent comprises adding an aqueous solution of a polyuronic acid, an alginic acid, a plant gum, or a partially methoxylated galacturonic acid or salt thereof to a BaSO4 suspension not more than 24 hours prior to its use in X-ray examination. Specified plant gums are gum arabic, karaya, ghatti, tragacanth and carragheen, and the exemplified partially methoxylated galacturonic acid is pectin sorbitol or mannitol may be added to the adjuvant solution together with an appropriate preserving agent, e.g. SO2 or sodium benzoate.
