Dual-energy computed tomography in diagnosis of gout

The aim of this study is to investigate the diagnostic efficiency of dual-energy computed tomography in the diagnosis of gout, including different stages of the disease. The study includs 91 patients with suspected gout, who underwent feet scanning including ankle areas. Dual-energy computed tomography showed high sensitivity, specificity and accuracy (88.5%, 86.6% and 87.9%, respectively). Depending on the course of the disease, dual-energy computed tomography shows a tendency to decrease sensitivity at the onset of the disease (73.6%), whereas at a longer duration of the disease, the sensitivity is high (95%).
