Clinical Characteristics, Brain MRI Findings, and Diagnostic Approach of the Central Nervous System Vasculitis by Affected Vessel Size
Background/Purpose: Diagnosis of the central nervous system vasculitis (CNS-V) is made on the basis of image findings or brain biopsy. Recently, two different subtypes of…Abstract Number: 1112 • ACR Convergence 2020
Relationship of Depth-Specific Subchondral Bone Mineral Density and Pain in Knee Osteoarthritis: The Multicenter Osteoarthritis Study
Background/Purpose: OA has traditionally been considered a disease of cartilage but early OA changes in subchondral bone may precede cartilage abnormalities. Altered subchondral bone mineral…Abstract Number: 1540 • ACR Convergence 2020
Association Between Disease Activity and Left Ventricular Systolic Function in Patients with Rheumatoid Arthritis: A Case-Control Study
Background/Purpose: Patients with Rheumatoid Arthritis(RA) have a higher prevalence of Cardiovascular Disease (CVD), which is the most common cause of death in this group. Disease…Abstract Number: 1564 • ACR Convergence 2020

Background/Purpose: The uEXPLORER system enables the unique, simultaneous acquisition of PET data over the entire adult human body with a high-sensitivity, alongside concurrent CT data.…Abstract Number: 0411 • ACR Convergence 2020
Serial Vessel Wall Enhancement Change on High-Resolution MRI Vessel Wall Imaging in Primary Central Nervous System Vasculitis
Background/Purpose: High-resolution vessel wall imaging (HR-VWI) is emerging as a tool of notable utility in the diagnosis of central nervous system vasculitis (CNS-V). However, little…Abstract Number: 1118 • ACR Convergence 2020
Bone Marrow Lesion Scores in Patients with Knee Osteoarthritis Undergoing Tibial Osteotomy: Reliability and Concurrent Validity of the Knee Inflammation MRI Scoring System (KIMRISS)
Background/Purpose: Bone marrow lesions (BMLs) commonly occur in knee osteoarthritis (OA) and are associated with increased risk of cartilage damage and pain. The Knee Inflammation…Abstract Number: 1542 • ACR Convergence 2020
The Role of Dual Energy Computed Tomography (DECT) in the Differentiation of Gout and Calcium Pyrophosphate Deposition Disease
Background/Purpose: Differentiation of gout and calcium pyrophosphate deposition disease (CPPD) is sometimes difficult as patients often present with a similar clinical picture. Arthrocentesis and subsequent…Abstract Number: 1731 • ACR Convergence 2020
Development of a Disease Activity Index for Rheumatoid Arthritis Patients Using the HandScan
Background/Purpose: Disease activity in rheumatoid arthritis (RA) patients is usually measured by an index like DAS28,1 a composite measure consisting of 28 swollen and/or tender…Abstract Number: 0445 • ACR Convergence 2020
Dual-Energy CT in Gout Patients: Do All Color-Coded Lesions Actually Represent Monosodium Urate Crystals?
Background/Purpose: Dual-Energy CT (DECT) can acknowledge differences in tissue compositions and can color-code tissues with specific features including monosodium urate (MSU) crystals. However, when evaluating…Abstract Number: 1162 • ACR Convergence 2020
