Bone Tissue in Magnetic Resonance Imaging: Contribution of New Zero Echo Time Sequences.
Semin Musculoskelet Radiol
August 2023
The introduction of new ultrashort and zero echo time (ZTE) sequences is revolutionizing magnetic resonance imaging (MRI) and optimizing patient management. These sequences acquire signals in tissues with very short T2: mineralized bone, cortical bone, and calcium deposits. They can be added to a classic MRI protocol.

Methods: Baseline imaging of the sacroiliac joints (X-SI), MRI of the sacroiliac joints (MRI-SI) and MRI-spine were scored by ≥2 experienced central readers per modality in the SPondyloArthritis Caught Early (SPACE) and DEvenir des Spondylarthropathies Indifférenciées Récentes (DESIR) cohorts. Inflammation suggestive of axSpA was assessed in the entire spine.
Article Synopsis
- The study aimed to see how reliable local doctors are at identifying specific changes in MRI scans of patients with back pain suggestive of a condition called axial spondyloarthritis.
- It involved comparing the results from local readers with those of trained experts to see if they agreed on the findings.
- The results showed that the agreement between local and expert readings was mostly fair, but got better when certain types of lesions were considered.
Article Synopsis
- The study looks at how MRI scans of the sacroiliac joints can help in diagnosing a type of arthritis called axial SpondyloArthritis (axSpA).
- The researchers tested different ways to use MRI results alongside or instead of traditional X-ray methods to see if they improve the diagnosis.
- They found that MRI can be reliable for diagnosis, but changing from X-rays to MRI might not affect most patients' classifications for axSpA.
Objective: To evaluate the rate of radiographic structural progression in the sacroiliac (SI) joints in patients with radiographic or nonradiographic axial spondyloarthritis (SpA), and to determine factors predisposing to such progression, over 2 years.
Methods: Patients with recent-onset axial SpA (from the Devenir des Spondyloarthropathies Indifferérenciées Récentes cohort) were assigned a radiographic SI joint score according to the modified New York criteria. Demographic characteristics, smoking status, HLA-B27 positivity, inflammation on magnetic resonance imaging (MRI) of the SI joints, disease activity, and treatment were investigated as potential predisposing factors.
