Comparative study of iohexol and meglumine iothalamate in double-contrast knee arthrography.

A comparison has been made between meglumine iothalamate and a low-osmolar contrast medium, iohexol, in arthrography of the knee. A controlled study evaluated the immediate and delayed patient response as well as the quality of the examination, which was assessed by two radiologists without knowledge of which contrast medium had been employed. The results show that iohexol is a good contrast medium for knee arthrography but offers no advantages to offset the increased cost compared with contrast media in current use.
