The addition of steroids and/or anesthetics to gadolinium solutions for MR arthrography does not substantially impact signal intensity. When gadolinium is diluted into a 50% or greater strength of iohexol, the signal intensity curve shifts so that the maximum signal intensity is obtained with lower gadolinium concentrations (0.625-1.25 mmol/L).

The use of an intraarticular anesthetic significantly reduces periprocedural pain and major motion artifacts associated with MR shoulder arthrography; however, total MR imaging time is not reduced.
