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.
