Abstract:Background:Axial spondyloarthritis (axSpA) is a chronic inflammatory disease that typically affects the axial joint and enthesis. Abnormal hyperplasia of osteoblasts in the vertebral corner is the underlying pathogenesis of syndesmophyte formation. Therefore, detecting abnormal osteoblast hyperactivity in the axial joints of patients with axSpA might be an attractive imaging modality to detect potential of spinal structural progression. Bone scintigraphy is used to evaluate the sites of active bone formation b… Show more
