Boerdalen, Bjoern E. published the artcileOsmotic properties of some contrast media, Safety of 2-(3,5-Diiodo-4-oxopyridin-1(4H)-yl)acetic acid, the publication is Investigative Radiology (1970), 5(6), 559-65, database is CAplus and MEDLINE.
The contrast media, when compared on the basis of I concentration, showed only minor differences in osmolality and water activity when calculated from concentrations and osmotic coefficients A plot of osmolality vs. I concentration for different contrast media showed a slightly curved line with Angio-Conray at the top and isopaque 260 at the bottom. The mols. of some of the contrast media deviated from the theoretically assumed spherical sym.
