Background The severity of Rheumatoid Arthritis (RA) is associated with increased fracture risk (1). Areal bone mineral density (aBMD) by dual-energy absorptiometry (DXA) the gold standard for diagnosis osteoporosis as well assessment. High resolution peripheral quantitative computed tomography (HR-pQCT) distal radius yields volumetric BMD (vBMD) trabecular and cortical compartments, micro-arch...
