Overview
There are no MRI findings associated with cutaneous psoriasis, but MRI may be used in psoriatic arthritis (PsA) to diagnose the disease in its early phase.
MRI
MRI in psoriatic arthritis may show the following findings:[1]
- Joint erosion
- Synovitis (usually secondary to extrasynovial involvement, helps to differentiate PsA from rheumatoid arthritis)
- Gadolinium contrast use can more reliably differentiate PsA from rheumatoid arthritis by relative enhancement and rate of enhancement on MRI
- Enthesitis
- Osteitis
- Peri-articular edema
