Objective.To evaluate whether features of radiographic hand osteoarthritis (OA) are associated with quantitative magnetic resonance imaging (MRI)-defined knee cartilage thickness, radiographic knee OA, and 1-year structural progression.Methods.A total of 765 participants in Osteoarthritis Initiative (OAI; 455 women, mean age 62.5 yrs, SD 9.4) obtained hand radiographs (at baseline), knee radiographs (baseline and Year 1), and knee MRI (baseline and Year 1). Hand radiographs were scored for presence of osteophytes and joint space narrowing (JSN). Knee radiographs were scored according to the Kellgren-Lawrence (KL) scale. Cartilage thickness in the medial and lateral femorotibial compartments was measured quantitatively from coronal FLASHwe images. We examined the cross-sectional and longitudinal associations between features of hand OA (total osteophyte and JSN scores) and knee cartilage thickness, 1-year knee cartilage thinning (above smallest detectable change), presence of knee OA (KL grade ≥ 3), and progression of knee OA (KL change ≥ 1) by linear and logistic regression. Both hand OA features were included in a multivariate model (if p ≤ 0.25) adjusted for age, sex, and body mass index (BMI).Results.Hand JSN was associated with reduced knee cartilage thickness (ß = −0.02, 95% CI −0.03, −0.01) in the medial femorotibial compartment, while hand osteophytes were associated with the presence of radiographic knee OA (OR 1.10, 95% CI 1.03–1.18; multivariate models) with both hand OA features as independent variables adjusted for age, sex, and BMI). Radiographic features of hand OA were not associated with 1-year cartilage thinning or radiographic knee OA progression.Conclusion.Our results support a systemic OA susceptibility and possibly different mechanisms for osteophyte formation and cartilage thinning.

Magnetic resonance imaging (MRI) overcomes many of the limitations associated with conventional radiography, the technique historically regarded as the gold standard in imaging of osteoarthritis (OA). MRI allows visualization of changes and pathologies in joint tissues including cartilage and the menisci, the two tissue components responsible for the indirect radiographic marker of joint space narrowing, decreasing the length of time that must elapse before disease progression can be detected. Other elements of the joint can also be analysed simultaneously: a key development in the understanding of OA. This chapter focuses on the utility of MRI in observational studies and clinical trials, detailing the available MRI techniques and quantitative/qualitative measurements, and their correlation with tissue damage. The possible future directions of MRI in OA are also discussed, with a view to its potential utility in identifying disease-modifying interventions.

Objective.To test the intrareader and interreader reliability of assessment of joint space narrowing (JSN) in rheumatoid arthritis (RA) wrist and metacarpophalangeal (MCP) joints on magnetic resonance imaging (MRI) and computed tomography (CT) using the newly proposed OMERACT-RAMRIS JSN scoring method, and to compare JSN assessment on MRI, CT, and radiography.Methods.After calibration of readers, MRI and CT images of the wrist and second to fifth MCP joints from 14 patients with RA and 1 healthy control were assessed twice for JSN by 3 readers, blinded to clinical and imaging data. Radiographs were scored by the Sharp/van der Heijde method. Intraclass correlation coefficients (ICC) and smallest detectable differences (SDD) were calculated, and the performance of various simplified scores was investigated.Results.Both MRI and CT showed high intrareader (ICC ≥ 0.95) and interreader (ICC ≥ 0.94) reliability for total (wrist + MCP) assessment of JSN. Agreement was generally lower for MCP joints than for wrist joints, particularly for CT. Intrareader SDD for MCP/wrist/MCP + wrist were 1.2/6.1/6.4 JSN units for MRI, while 2.7/8.3/9.9 JSN units for CT. JSN on MRI and CT correlated moderately well with corresponding radiographic JSN scores (MCP 2–5: 0.49 and 0.56; wrist areas assessed by Sharp/van der Heijde: 0.80 and 0.95), and high ICC between scores on MRI and CT were demonstrated (MCP: 0.94; wrist: 0.92; MCP + wrist: 0.92).Conclusion.The OMERACT-RAMRIS MRI JSN scoring system showed high intrareader and interreader reliability, and high correlation with CT scores of JSN. The suggested JSN score may, after further validation in longitudinal studies, become a useful tool in RA clinical trials.

Objective.To assess the intrareader and interreader agreement and sensitivity to change of the Outcome Measures in Rheumatology (OMERACT) Rheumatoid Arthritis Magnetic Resonance Imaging Joint Space Narrowing (RAMRIS-JSN) score in the rheumatoid arthritis (RA) wrist in a longitudinal multireader exercise.MethodsCoronal T1-weighted MR image sets of 1 wrist from 20 patients with early RA were assessed twice for JSN at 17 sites at baseline and after 36 or 60 months by 4 readers blinded to patient data but not time order. The joints were scored 0–4 according to the OMERACT RAMRIS-JSN score. Intraclass correlation coefficients (ICC), smallest detectable change (SDC), percentage exact/close agreement (PEA/PCA), and standardized response mean (SRM) were calculated.Results.Median baseline and change score was 10.3 and 1.9, respectively. Intrareader ICC for baseline and change scores was good (≥ 0.50) to very good (≥ 0.80) for all and 3 of 4 readers, respectively. Interreader ICC was very good for change (0.93), while poor for baseline score if all 4 readers were included (0.36), but very good if 1 reader was excluded (0.87). Intrareader and interreader SDC was low (2.34–3.18), except for the intrareader SDC for 1 reader (6.75). The mean PEA/PCA was high for baseline and change scores both within and between the readers (51.5–99.2), except for interreader baseline PEA (14.4). SRM was moderate for all readers (0.55–0.77).Conclusion.The OMERACT RAMRIS-JSN score showed high overall intrareader and interreader reliability, and moderate sensitivity to change, supporting inclusion of the measure as part of the OMERACT RAMRIS system.
