Workshop report: clinical diagnosis and imaging of sacroiliitis, Innsbruck, Austria, October 9, 2003

Confirmation of sacroiliitis in clinical practice is based on various imaging techniques. Sacroiliitis detected by radiography, magnetic resonance imaging (MRI), or computerized tomography (CT) in the presence of clinical manifestations is diagnostic of ankylosing spondylitis (AS). The cooperation between rheumatologists, radiologists, and nuclear medicine specialists can be crucial for future developments. The techniques currently used in the diagnosis of sacroiliitis are discussed in this review and an algorithm is proposed for the use in clinical practice.
