Objective: To investigate the association of change in thigh muscle volume (TMV) with structural knee changes and changes in knee pain and functional limitation over 48 months. Design: Deep learning-based automated segmentations were used to quantify magnetic resonance imaging-derived TMV at baseline …

Abstract Clinical deployment of medical imaging artificial intelligence (AI) requires objective and continuous quality assurance, yet standardised methods for this purpose have not been established. Here, we present a framework using physical phantoms for standardised on-site testing and monitoring of AI, demonstrated …

Objective: To investigate whether the 48-month change in effusion-synovitis volume (ΔESV) is associated with concurrent knee osteoarthritis progression, and to compare these associations with those of semiquantitative change in effusion-synovitis using the MRI Osteoarthritis Knee Score (ΔMOAKS). Design: In this study using …

Background: According to current recommendations, patients with suspected axial Spondyloarthritis (axSpA) typically undergo initial radiography of the sacroiliac joint (SIJ), followed by magnetic resonance imaging (MRI) if the radiograph is negative [1]. However, X-rays (XR) of the SIJ are known for their …

Computed tomography (CT) has traditionally been underutilized in the imaging of inflammatory arthritis due to its limitations in assessing soft tissue inflammation and concerns over radiation exposure. However, recent technological advancements have positioned CT as a more viable imaging modality for arthritis, …
