Diagnostic Accuracy of Muscle MRI for Muscular Vasculitis in Anti-neutrophil Cytoplasmic Antibody-associated Vasculitis: A Pilot Study
Background/Purpose: Histopathologic confirmation is the golden standard for diagnosis of anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV), but sometimes can be difficult because of its invasion (e.g.…Abstract Number: 1368 • ACR Convergence 2021
Characterising Exercise Capacity in Systemic Sclerosis Using Cardiac Magnetic Resonance Imaging, Skeletal Muscle Imaging and Cardiopulmonary Exercise Testing
Background/Purpose: Impaired exercise capacity contributes to functional impairment, negatively impacting individuals’ quality of life. Functional impairment is notable from early in the disease course of…Abstract Number: 0155 • ACR Convergence 2021
The Additional Value of MRI in Diagnosis of Rheumatoid Arthritis in Undifferentiated Arthritis Patients
Background/Purpose: Identifying patients that will develop rheumatoid arthritis (RA) among those presenting with undifferentiated arthritis (UA) remains a clinical dilemma. According to EULAR recommendations magnetic…Abstract Number: 0456 • ACR Convergence 2021
Functional Connectivity, Enhanced Blood-Brain Barrier Leakage and Cognitive Impairment in Systemic Lupus Erythematosus
Background/Purpose: Cognitive impairment is the most frequent manifestation of neuropsychiatric systemic lupus erythematosus (NPSLE), yet the mechanisms underlying it remain poorly understood. We have previously…Abstract Number: 1474 • ACR Convergence 2021
Automatic Detection of Bone Marrow Lesions from Knee MRI Data from the OAI Study
Background/Purpose: Subchondral bone marrow lesions (BMLs) are associated with symptoms and structural progression of knee OA. BMLs are characterized by diffuse hyperintensity on fat suppressed…Abstract Number: 0157 • ACR Convergence 2021
Development of a Deep Learning Algorithm for the Detection of Sacroiliitis on MRI in Patients with Active Axial Spondyloarthritis
Background/Purpose: Magnetic resonance imaging (MRI) plays a critical role in assisting the diagnosis of axial spondyloarthritis (axSpA). There are many characteristic MRI lesions that can…Abstract Number: 0468 • ACR Convergence 2021
During Development of Rheumatoid Arthritis, Intermetatarsal Bursitis May Occur Before Clinical Joint Swelling: A Large MRI Study in Patients with Clinically Suspect Arthralgia
Background/Purpose: Inflammation of the synovial lining is a hallmark of rheumatoid arthritis (RA). A synovial lining is not only present at synovial joints and tendon…Abstract Number: 1864 • ACR Convergence 2021
18F-Fluorodeoxyglucose PET/MRI as an Alternative Hybrid Imaging Modality: Comparative Study in a Prospective, Longitudinal Cohort of Patients with Large-Vessel Vasculitis
Background/Purpose: Imaging modalities play an important role in the diagnosis and management of patients with large-vessel vasculitis (LVV). Use of 18F-fluorodeoxyglucose (FDG) positron emission tomography…Abstract Number: 1113 • ACR Convergence 2020
Intrameniscal Signal Alterations Strongly Predict Destabilizing Meniscal Tears and Accelerated Knee Osteoarthritis: Data from the Osteoarthritis Initiative
Background/Purpose: It is unknown whether early changes in the menisci (e.g., intrameniscal signal alterations) have long-term consequences. We conducted a study to assess the prognostic…Abstract Number: 1557 • ACR Convergence 2020
Lymphatics as a Biomarker of Joint Physiology: Near-Infrared Imaging of Indocyanine Green Identifies Novel Routes of Lymphatic Drainage from Metacarpophalangeal Joints in Healthy Human Hands
Background/Purpose: In our previous work, we discovered that patients with active hand RA have reduced lymphatic drainage of indocyanine green (ICG) from the web spaces…Abstract Number: 1114 • ACR Convergence 2020
Longitudinally Assessed Structural Abnormalities on MRI and Relative Contributions to Risk of Incident Radiographic Knee Osteoarthritis over 10 Years of Follow-up
Background/Purpose: MRI has identified joint tissues affected during knee OA development, though the relative importance of structures in the pathogenic process is unknown. Our objective…Abstract Number: 1562 • ACR Convergence 2020
Subclinical Joint Inflammation of Hands by Magnetic Resonance Imaging in Patients with Psoriatic Arthritis in Clinical Remission Compared to Active Disease
Background/Purpose: Assessment of disease activity in psoriatic arthritis (PsA) is based on tender and swollen joint counts (TJC and SJC, respectively). Yet, the prevalence of…Abstract Number: 1115 • ACR Convergence 2020
The Relation of MRI-Based Cartilage Lesions to Knee Replacement and Knee Pain Severity in Osteoarthritis: The Multicenter Osteoarthritis Study
Background/Purpose: Recently, the FDA has indicated that data supporting imaging biomarkers of relevance to clinically important outcomes, such as knee replacement (KR) may be considered…Abstract Number: 1713 • ACR Convergence 2020
Exploring Novel Tenosynovitis and Combined Inflammation Imaging Outcomes: Results from a Randomized Controlled Trial in Early Rheumatoid Arthritis
Background/Purpose: MRI trial outcomes have largely focused on synovitis, bone marrow edema (BME), and erosions. Tenosynovitis is a common manifestation of RA, but is relatively…Abstract Number: 1116 • ACR Convergence 2020
Magnetic Resonance Imaging Structural Changes Correlated with Knee Extension: Data from the Osteoarthritis Initiative
Background/Purpose: Knee OA is often accompanied by loss of passive extension, termed a flexion contracture (FC), resulting in worse clinical outcomes. To our knowledge, MRI-based…
