In
the present 3T study, DCE-MRI was evaluated in the differential diagnosis of
psoriatic arthritis (PsA) and erosive arthritis (EOA) of the hand in 26
patients. Significantly higher late enhancement was observed in EOA patients
15 minutes after contrast injection. Results suggest that analysis of
synovial membrane inflammation by DCE-MRI could be useful in the
differentiation of these two arthritis types which is often difficult based
on clinical and laboratory findings alone. As new treatment approaches are
particularly adapted for each arthritis entity DCE-MRI could provide
additional diagnostic information in differentiating PsA from EOA in clinical
routine.
