Coronal short tau inversion recovery (STIR) post-contrast fat-saturated coronal three-dimensional T1-weighted gradient-echo magnetic resonance image (MRI) at 1.5T. Periarticular soft tissue T2 hyperintensity and enhancement around both shoulder and knee joints (arrows) suggesting active synovitis are identified on STIR (A) and post-contrast fat-saturated T1-weighted gradient echo (B) whole-body MRIs at 1.5T.
