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: 0179 • ACR Convergence 2021
Impaired Myocardial Flow Reserve on 82Rubidium Positron Emission Tomography Imaging Predicts Adverse Events in Patients with Autoimmune Rheumatic Disease
Background/Purpose: Coronary microvascular dysfunction (CMVD) has been described in patients with autoimmune rheumatic disease (ARD). By noninvasive evaluation of myocardial blood flow (MBF) and myocardial…Abstract Number: 0906 • ACR Convergence 2021
Measurement of Vertebral Hounsfield Units in Low Dose Computed Tomography – a Reliable Methodology for Assessing Bone Mineral Density at the Vertebral Level in Patients with Radiographic Axial Spondyloarthritis
Background/Purpose: Bone loss paradoxically coexists with bone formation in radiographic axial spondyloarthritis (r-axSpA). Assessing bone mineral density (BMD) in r-axSpA poses challenges, namely because of…Abstract Number: 1886 • ACR Convergence 2021
Validation of Angiographic Patterns of Disease in a Turkish Cohort of Patients with Takayasu’s Arteritis
Background/Purpose: Previous studies using computer-driven methods have identified subsets of patients with Takayasu’s arteritis based on angiographic patterns of disease. These subsets were consistent between…Abstract Number: 0150 • ACR Convergence 2021
Clinical Characteristics and Quantitative CT Findings in Connective Tissue Disease-Associated Interstitial Lung Disease
Background/Purpose: Precapillary Pulmonary Hypertension (PPH) is a known complication of connective tissue disease-associated interstitial lung disease (CTD-ILD) but at present requires right heart catheterization (RHC)…Abstract Number: 0180 • ACR Convergence 2021
Impaired Myocardial Flow Reserve on 82Rubidium Positron Emission Computed Tomography in Patients with Systemic Sclerosis
Background/Purpose: To investigate the association between Raynaud phenomenon (RP) and coronary microvascular dysfunction, we measured myocardial flow reserve (MFR) using positron emission tomography/computed tomography (PET/CT)…Abstract Number: 0975 • ACR Convergence 2021
Data-driven MRI Definitions for Active and Structural Sacroiliac Joint Lesions in Juvenile Spondyloarthritis Typical of Axial Disease
Background/Purpose: Determining optimal cut-offs for active and structural imaging lesions of juvenile spondyloarthritis (JSpA) with axial disease is important for diagnosis, therapeutic management, and classification.…Abstract Number: 1919 • ACR Convergence 2021
Detection of Radiographic Sacroiliitis with an Artificial Neural Network in Patients with Suspicion of Axial Spondyloarthritis
Background/Purpose: Conventional radiography of the sacroiliac joints is still recommended as the first imaging method for the diagnosis of axial spondyloarthritis (axial SpA). In many…Abstract Number: 0151 • ACR Convergence 2021
Usefulness of Ultrasound and (FDG) PET/CT to Detect Cranial and Extracranial Artery Involvement in Patients with Suspected Large Vessel Vasculitis
Background/Purpose: Ultrasound (US) is recommended as the first imaging modality to assess patients presenting with predominantly cranial symptoms of giant cell arteritis (GCA). However, its…Abstract Number: 0181 • ACR Convergence 2021
Magnetic Resonance Imaging Findings in Early Rheumatoid Arthritis: Are There Differences Based on Autoantibody Status?
Background/Purpose: Magnetic resonance imaging (MRI) is increasingly used as an adjunct to the physical examination in early rheumatoid arthritis (RA). Characteristic differences in MRI findings…Abstract Number: 1170 • ACR Convergence 2021
Establishment and Validation of a Didactic Musculoskeletal Ultrasound Course for Dermatologists Using an Innovative Handheld Ultrasound System
Background/Purpose: In the early detection of arthritis, such as psoriatic arthritis, ultrasound (US) of painful joints plays an important role in diagnosis. Pathological findings can…Abstract Number: 0152 • ACR Convergence 2021
Deep Learning-Derived Chest Radiograph Scores in COVID-19 in Rheumatic Disease Patients versus General Population Comparators
Background/Purpose: Patients with rheumatic diseases and COVID-19 may have higher risk of mechanical ventilation than those without rheumatic diseases. We compared COVID-19 lung disease between…Abstract Number: 0213 • ACR Convergence 2021
Quantitative Assessment of Volumetric Change in Hip Effusion Using Artificial Intelligence in Patients with Osteoarthritis of the Hip
Background/Purpose: Accurate quantification of hip effusion volume may aid effective OA management as synovitis of the hip has been associated with pain and structural damage…
