The reliability of the RAMRIS for metatarsophalangeal (MTP 1–5) joints has been explored in this study.
Till now, Rheumatoid Arthritis
Magnetic Resonance Imaging Score (RAMRIS) has been authenticated for use
in the metacarpophalangeal (MCP) and wrist joints, but not in
metatarsophalangeal (MTP) joints. The
outcomes of this study provide encouraging results regarding the use of scoring
systems for MTP joints in trials in early
phases of rheumatoid arthritis (RA). A good to excellent intra- and interreader
reliability for status and change scores was observed, with special reference
to a > 0.90 score of ICC for the
inflammatory features.
The reliability
of the RAMRIS for metatarsophalangeal (MTP 1–5)
joints has been explored in this study.
The patients with clinically confirmed arthritis and symptom duration < 2 years who were naive to DMARD underwent 1.5 Tesla MRI of MTP, metacarpophalangeal (MCP 2–5), and the wrist joints. The bone marrow edema (BME), synovitis, tenosynovitis, and erosions (MRI outcomes) were studied.
The following flowchart of
patient selection has been portrayed in below figure:
The Bland-Altman (BA)
plots, intraclass correlation coefficients (ICC), and smallest detectable change
(SDC) were all noted. A comparison of MRI data of MTP joints was done with wrist
and MCP joints.
In early arthritis, the
interreader ICC and mean scores were BME ICC
0.91–0.92, erosions 0.88–0.89 and tenosynovitis 0.80–0.8. These coefficients were
similar in patients with clinically suspicious arthralgia.
The intrareader ICC for
inflammatory
The RAMRIS can be used to
reliably evaluate the status and variation of MRI outcomes.
