Comparison of Sacroiliac CT Findings in Patients with and Without Ankylosing Spondylitis Aged 50 Years or Older: Preliminary Results of the CASIAGE Study
Background/Purpose: Diagnosis of axial spondyloarthritis (SpA) is nowadays commonly made with pelvic radiography or MRI. However, there is an important inter-observer variability for radiographs, and…Abstract Number: 0901 • ACR Convergence 2021
Low Dose Dual Energy CT Scan for the Detection of Bone Marrow Edema and Erosions in Axial Spondyloarthritis
Background/Purpose: Bone marrow edema (BME) and erosions of the sacroiliac (SI) joints are key imaging features in the diagnosis of axial spondyloarthritis (axSpA). MRI with…Abstract Number: 1101 • ACR Convergence 2021
Atypical Pulmonary Radiographic Findings May Help Identify Patients with Usual Interstitial Pneumonia and Autoimmune Features
Background/Purpose: Once specific etiologic factors have been ruled out, the majority of patients with chronic interstitial pneumonia (IP) can be classified as idiopathic pulmonary fibrosis…Abstract Number: 0106 • ACR Convergence 2020
A Machine Learning-derived Radiomics Nomogram for Diagnosis of Osteoporosis and Osteopenia
Background/Purpose: To discriminate osteoporosis and osteopenia using a quantitative computed tomography (QCT) radiomics signatures and clinical variables.Methods: This retrospective study enrolled 635 patients with QCT images and clinical characteristics from November…Abstract Number: 1558 • ACR Convergence 2020
Cinematic Rendering Enables Depiction of Bone Anabolic Effects in Patients Treated with Baricitinib
Background/Purpose: Preclinical studies show that tsDMARDs such as baricitinib may be a therapeutic agent for bone anabolic effects by increasing osteoblast function in inflammatory conditions.[1]…Abstract Number: 0398 • ACR Convergence 2020
Chest CT Ordering Practices at Expert Scleroderma Centers in the United States
Background/Purpose: Interstitial lung disease (ILD) is the leading cause of death in patients with systemic sclerosis (SSc). Although pulmonary function tests (PFTs) are commonly used…Abstract Number: 1881 • ACR Convergence 2020
In Radiographic Axial Spondyloarthritis, Bridging Syndesmophytes Increase Risk of Facet Joint Ankylosis Development on the Same Vertebral Level While Facet Joint Ankylosis Does Not Increase Risk of Same Level Syndesmophytes Development
Background/Purpose: In radiographic axial spondyloarthritis (r-axSpA), spinal damage manifests as syndesmophytes and facet joint ankylosis (FJA). Whether there is an order in which lesion develops…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: 2034 • ACR Convergence 2020
Resolving Phenotypic and Prognostic Differences in Interstitial Lung Disease Related to Systemic Sclerosis by Computed Tomography-based Radiomics
Background/Purpose: Radiomics describes the in-depth analysis of tissue phenotypes by computational retrieval of high-dimensional quantitative imaging features including tissue intensity, texture, and wavelet characteristics. Here,…Abstract Number: 0485 • ACR Convergence 2020
Non-obese Rheumatoid Arthritis Patients with Low Low-density Lipoprotein Have Higher Coronary Atherosclerosis Burden, Greater Plaque Progression and Cardiovascular Event Risk
Background/Purpose: RA patients with low body weight incur higher mortality than obese patients. Paradoxically, RA patients in the lowest low-density lipoprotein group (LDL < 70…Abstract Number: 0486 • ACR Convergence 2020
Differences in Low-density Lipoprotein (LDL) Particle Composition and Oxidation May Underlie the Paradoxical Association of Low LDL with Higher Coronary Atherosclerosis Burden in Rheumatoid Arthritis
Background/Purpose: Rheumatoid arthritis (RA) patients in the lowest LDL group (< 70mg/dl) experience unexpectedly high cardiovascular risk. We first explored whether this group (Group 1)…Abstract Number: 0501 • ACR Convergence 2020
Structural Entheseal Lesions in Psoriasis Patients Are Associated with an Increased Risk Ofprogression to Psoriatic Arthritis – A Prospective Cohort Study
Background/Purpose: We have previously reported that the presence of musculoskeletal pain in psoriasis patients is associated with a higher risk of developing psoriatic arthritis (PsA)…Abstract Number: 0679 • ACR Convergence 2020
Epidemiology of Intra-Articular Mineralization on Knee Dual-Energy Computed Tomography: The Multicenter Osteoarthritis Study
Background/Purpose: Computed tomography (CT) has a higher sensitivity for the detection of intraarticular mineralization in comparison with commonly used imaging techniques in knee osteoarthritis (OA)…
