<qa>  What is the term for axial spondyloarthritis?A group of leading experts in the field of spondyloarthropathies proposed in 2004 the term axial spondyloarthritis as an attempt to narrow the gap of 5-10 years between the first symptoms and the diagnosis of AS Rudwaleit et al. Ann Rheum Dis 2004; 63:535-43. Using the proposed approach, an early diagnosis of AS or axial spondyloarthritis can be made with a high degree of confidence, when at least two to three spondyloarthritis features clinical findings, laboratory tests or skeletal imaging are present. Magnetic resonance imaging MRI of the sacroiliac joints appears to be especially useful tool in the diagnosis of early AS. Early diagnosis and treatment could probably prevent structural damage and lead to better functional outcomes.
