Defining and validating a high specificity MRI cut-off for the radiographic part of the modified New York criteria in patients with axial spondyloarthritis

A. E. F. Hadsbjerg, Simon Krabbe, Nora Vladimirova, Adrian Ciurea et autres

BACKGROUND: According to the modified New York criteria (mNYc), moderate-severe sacroiliac joint (SIJ) structural damage on radiography is necessary for classifying radiographic axial spondyloarthritis (r-axSpA). In contrast to radiography, MRI provides no ionizing radiation, higher sensitivity for structural damage, better inter-reader reliability, …

Standardised evaluation and monitoring of site-specific AI performance with physical CT phantoms

Ulrich Genske, Angelo Laudani, Li Yan, Yang Peng et autres

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 …

Prevalence and determinants of sacroiliac joint bone marrow oedema in the general population in Germany: a population-based cross-sectional study

Keno Bressem, Murat Torğutalp, Torsten Diekhoff, Nikolaos Kougkas et autres

Background MRI-detected bone marrow oedema in sacroiliac joints is central to diagnosing axial spondyloarthritis, influencing treatment decisions including anti-inflammatory therapy initiation. However, the prevalence of bone marrow oedema in the general population remains unknown, restricting interpretation of MRI findings and potentially leading …

High‐Resolution Deep Learning Dixon Magnetic Resonance Imaging of the Sacroiliac Joints Is Noninferior to Standard Magnetic Resonance Imaging in Patients With Suspected Axial Spondyloarthritis

Dominik Deppe, Mariam Koka, Fabian Proft, Sevtap Tugce Ulas et autres

OBJECTIVE: To compare the multisequence standard magnetic resonance imaging (sMRI) protocol of the sacroiliac joints with a single high-resolution deep learning-reconstructed Dixon sequence (DL-Dixon) in patients with suspected axial spondyloarthritis (axSpA). METHODS: Seventy-six patients with chronic low back pain and suspected axSpA …
