Dual-energy computed tomography scan in a patient presenting with right-sided acute ankle trauma. Standard grayscale series (a) does not depict any fracture line. Color-coded virtual non-calcium image (b) shows a distinct traumatic bone marrow edema of the right calcaneus, displayed as a green area (arrow). The finding was confirmed by magnetic resonance imaging (c) using a proton density-weighted sequence (arrow)
