Fifty-seven-year-old diabetic male patient presented with right dorsal foot swelling and redness with tarso-metatarsal instability and clinical suspicion of diabetic foot osteomyelitis. A Sagittal T2 SPAIR shows multi-focal bone marrow edema-like changes involving the mid-foot bones and the adjacent metatarsal bases (circle) with overlying dorsal subcutaneous edema signals. B–E Long axis T1-Dixon four-set images (IP, OP, fluid only and fat only images) demonstrate diffuse visual signal nulling of the affected bones in OP image (C) compared with IP image (B) and quantitative signal loss (signal intensity ratio = 0.26), note the Lisfranc dislocation (yellow arrow), features are consistent with neuropathic arthropathy without osteomyelitis
