Abstract

Objective: This study aimed to investigate the relationship between MRI T1 and T2 grayscale values and Sieper/Rudwaleit score with disease activity and inflammation levels in patients with ankylosing spondylitis (AS). Methods: Totally, 174 AS patients and 41 healthy controls were enrolled and received MRI and computed tomography (CT) of sacroiliac joints (SIJ). Results: Sieper/Rudwaleit score positively related to CT grade (p = 0.038). MRI T1 values correlated negatively and positively to MRI T2 values (p = 0.001) and CT grade (p = 0.016), respectively. According to multiple linear regression analysis, Sieper/Rudwaleit score showed an independent positive correlation with bone marrow fat deposition and Bath ankylosing spondylitis disease activity index (BASDAI) (both p < 0.001). MRI T1 values exhibited an independent positive correlation with male sex, duration of AS, and BASDAI; while they inversely related to C-reactive protein (CRP), platelets, albumin, and creatinine (all p < 0.05). MRI T2 values exhibited an independent positive correlation with CRP and neutrophils, and a negative correlation to age, male sex, and creatinine (all p < 0.05). CT grade disclosed an independent positive relationship with human leukocyte antigen B27 positivity, duration of AS, ankylosing spondylitis disease activity score, CRP, platelets, and alkaline phosphatase (all p < 0.05). Conclusion: MRI T1 and T2 values combined with the Sieper/Rudwaleit score may serve as potential biomarkers for evaluating inflammatory activity and disease progression in AS. CT serves as an adjunct to MRI to monitor the activity of AS.
