What is Early Identification of Sacroiliitis in Patients with Suspected Spondyloarthritis: about?

## Objective: The purpose of this study was to assess the performance of computed tomog-raphy (CT) scan and magnetic resonance imaging (MRI) for detecting sacroiliitis in non-radiographic SpA (nr-SpA). ## Methods: This cross-sectional monocentric double-blind study included 63 patients consulting for symptoms suggestive of SpA between February 2014 and February 2017. Patients with convention-al radiographs showing a confirmed sacroiliitis (grade 3 or 4) were not included. Eligible patients underwent CT and MRI of sacroiliac joints (SIJ). CT and MR images were interpreted by 2 experi-enced musculoskeletal radiologists blinded to clinical and laboratory data. Two professors in rheu-matology blinded to radiologists’ conclusions analyzed clinical data, laboratory tests, HLA typing, X-rays, CT and MRI images, and divided the patients into 2 groups: confirmed nr-SpA or no SpA. This classification was considered the gold standard when analyzing the results. ## Results: 46 women and 17 men were included in this study. 47 patients were classified as con-firmed nr-SpA (74.6%) and 16 patients as no SpA (25.4%). Sensitivity, specificity, and positive and negative predictive values of CT and MR
