MRI: Axial shoulder arthrogram (image 1 of 2)  
 

This image is a T1-weighted MRI with contrast injected into the joint space of the shoulder (arthrogram). The contrast material appears bright white. Fat usually appears bright in a T1-weighted image; however, a technique called 'fat saturation' has been employed in this image to make the fat in the tissues and bone marrow dark in order not to detract from the brightness seen in the joint space.
