Magnetic Resonance Imaging in Follow-up of Clinical Remission in Juvenile Idiopathic Arthritis
Background/Purpose: Despite clinical remission, a substantial proportion of Juvenile Idiopathic Arthritis (JIA) patients will flare after a period of inactive disease. MRI has proven to…Abstract Number: 1022 • 2012 ACR/ARHP Annual Meeting
Imaging of Ankle Joints by MRI in Murine Models of Inflammatory Arthritis
Background/Purpose: One of the fundamental shortcomings in the field of experimental rheumatology is the inability to non-invasively monitor the development of inflammatory arthritis longitudinally. Magnetic…Abstract Number: 1023 • 2012 ACR/ARHP Annual Meeting
Scoring Radiographic Progression in Axial Spa: Should We Use the Modified Stoke in Ankylosing Spondylitis Spine Score or the Radiographic Ankylosing Spondylitis Spinal Score?
Background/Purpose: Radiographic damage is one of the core outcomes in axial SpA and it is usually assessed with the modified Stoke Ankylosing Spondylitis (AS) Spine…Abstract Number: 1024 • 2012 ACR/ARHP Annual Meeting
What Constitutes the Characteristic Fat Lesion On MRI of the Sacroiliac Joints in Early Spondyloarthritis?
Background/Purpose: It is well known that fat infiltration (FI) of bone marrow may be observed on T1-weighted MRI in the sacroiliac joints (SIJ) of healthy…Abstract Number: 1025 • 2012 ACR/ARHP Annual Meeting
Spinal Inflammation in the Absence of SI Joint Inflammation On MRI in Patients with Active Non-Radiographic Axial Spondyloarthritis
Background/Purpose: The imaging arm of the ASAS axial spondyloarthritis (SpA) criteria requires the presence of sacroiliitis on MRI or radiographs. In patients (pts) with non-radiographic…Abstract Number: 1026 • 2012 ACR/ARHP Annual Meeting
