Answer

Currently, computed tomography (CT) has a minimal role in treating RA of the hands. Although CT is useful for demonstrating bony pathology, erosions in the small joints of the hands are evaluated best by using a combination of radiography and MRI. MRI also has the added advantage of being able to visualize bone marrow edema and synovial and soft-tissue involvement.
