Assessment of structural lesions, synovitis and bone marrow lesions in erosive hand osteoarthritis on MRI (0.3T) compared to the radiographic anatomical Verbruggen-Veys score
Abstract : Objective: To evaluate prevalence of structural lesions, synovitis and bone marrow lesions (BMLs) on MRI performed with a 0.3T imaging system in patients with erosive hand osteoarthritis (EHOA) and to compare them to the anatomic radiographic Verbruggen-Veys score (VV).
Design: For this Cross-sectional study, fifty-five EHOA patients were studied with 0.3T contrast-enhanced MRI and radiography (RX) of their dominant hand. Structural lesions were scored according to the OMERACT Hand Osteoarthritis MRI Scoring System as follows: osteophytes and erosions were graded from 0 to 3. On joint destruction lesion synovitis and BMLs were graded from 0 to 1. And on MRI, we evaluated the presence of several structural features: N: normal, O: osteophytic lesions, E: erosive lesions, E/O: osteophytic and erosive lesions and D: joint destruction. RX was scored according to the VV system. Relations between MRI features and VV stages were analysed.
Results: MRI identified more structural lesions than RX (77.3% versus 74.8%) and particularly more erosive lesions (E or E/O) than VV Phase E (33.5% versus 20.2%). E/O and D were mostly found on MRI. Synovitis and BMLs were significantly associated with E/O and D with the following odds ratios (ORs): 8.4 (95% CI 1.8-13.6); OR: 13.7 (95% CI 2.9-21.0); OR: 15.7 (95% CI 3.2-23.5); OR: 38.5 (95% CI 9.5-57.0), respectively.
Conclusion: MRI 0.3T appears completely relevant for EHOA lesion analysis. First, MRI shows more erosive lesions than RX in EHOA; second, it allows for the analysis of synovitis and BMLs to be associated with more specific structural MRI features (E/O and D).
