What is an Arthrogram?

 

An MR Arthrogram is a study made on the articulations with the MRI equipment in which a substance is injected permitting greater contrast and more details of the anatomical area being evaluated. An MR Arthrogram helps assess certain pathological conditions on the articulations.

​

Direct MR Arthrogram - The gadolinium or saline solution is injected directly in the articulation.

​

Indirect MR Arthrogram - In case a Direct MRA is not convenient or can´t be performed due to logistic reasons, the gadolinium is injected intravenously. Although it is not as convenient as a Direct MRA, an indirect MRA is superior to the conventional MRI regarding the details of the structures being evaluated.
