Objective: Conventional magnetic resonance imaging (MRI) uses T1-weighted and short-tau inversion recovery (STIR) sequences to characterize bone marrow in axial spondyloarthritis. However, quantification is restricted to estimating the extent of lesions because signal intensities are highly variable both within individuals and across patients and MRI scanners. This study evaluates the performance of quantitative T1 mapping for distinguishing different types of bone marrow lesions of the sacroiliac joints.

- The study compared MRI and CT scans of the sacroiliac (SI) joint spaces in patients with axial spondyloarthritis to understand inflammation and potential new bone formation.
- Researchers categorized MRI joint lesions into three types, measuring the Hounsfield units (HU) to assess their density compared to surrounding bone and cartilage.
- Findings indicated that all lesion types displayed increased density, indicating potential new bone formation, with type C lesions showing the highest density and calcified matrix.
