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: 0158 • ACR Convergence 2021
The Influence of Age on the Prevalence of Inflammatory and Post-inflammatory MRI Lesions in the Sacroiliac Joints of Patients with and Without Axial Spondyloarthritis
Background/Purpose: Axial spondyloarthritis (axSpA) is clinically characterized by chronic inflammatory back pain and by inflammatory and structural changes in the sacroiliac joint (SIJ) as assessed…Abstract Number: 0469 • ACR Convergence 2021
Imaging Characteristics in Patients with Spondyloarthritis Using a Novel Heel Enthesitis Magnetic Resonance Imaging Scoring (HEMRIS) System: Post-hoc Analysis of a Phase 3 Secukinumab Trial
Background/Purpose: The heel is a frequently affected anatomical site for enthesitis in spondyloarthritis (SpA).1 Recently, the Outcome Measures in Rheumatology (OMERACT) group developed and validated…Abstract Number: 1921 • ACR Convergence 2021
Axial Psoriatic Arthritis: Correlation Between Whole Spine MRI Abnormalities and Clinical Findings
Background/Purpose: Psoriatic Arthritis (PsA) typically affects peripheral joints, but in some patients the disease can involve the spine. While magnetic resonance imaging (MRI) is an…Abstract Number: 0161 • ACR Convergence 2021
Does 18F-FDG-PET/MRI Add Metabolic Information to Anatomic Image in Childhood-onset Takayasu’s Arteritis Patients? A Multicenter Case Series
Background/Purpose: The disease activity assessment in c-TA is a challenge in clinical practice, especially in patients who are under immunosuppression. Our aim was to perform…Abstract Number: 0710 • ACR Convergence 2021
Patients with Recent Onset, Active Polymyositis (PM), Dermatomyositis (DM) and Antisynthetase Syndrome (ASS) Have Reduced Muscle Endurance but Not Reduced Muscle Strength Compared to Patients with Established, Low-active Disease
Background/Purpose: To analyze for differences in quadriceps maximal isometric voluntary contraction (MVIC), muscle endurance (ME), muscle mass and fat mass (m. vastus lateralis, mid-thigh) in…Abstract Number: 0162 • ACR Convergence 2021
Cardiac Magnetic Resonance Imaging for Guiding Decision-making on Treatment Duration: Data from RHAPSODY, a Phase 3 Clinical Trial of Rilonacept in Recurrent Pericarditis
Background/Purpose: The magnitude of pericardial delayed hyperenhancement (DHE) by cardiac magnetic resonance imaging (CMR) illustrates the severity of inflammation in pericarditis. We hypothesized that patients…Abstract Number: 0852 • ACR Convergence 2021
Bone Marrow Lesion Segmentation Using Synthetic Data and Deep Learning Models
Background/Purpose: Bone marrow lesions (BML) are indicators for knee osteoarthritis (OA) and can be detected from magnetic resonance imaging (MRI). Due to the small size,…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: 0898 • ACR Convergence 2021
MRI Vertebral Corner Inflammation and Fat Deposition Are Associated with Whole Spine Low Dose CT Detected Syndesmophytes: A Multilevel Analysis
Background/Purpose: In previous studies vertebral corner inflammation (VCI) and vertebral corner fat deposition (VCFD) were associated with syndesmophyte formation on cervical and lumbar conventional radiography.…
