Abstract: 100 patients with gouty arthritis who were treated in our hospital from May 2017 to May 2019 were enrolled. All patients underwent dual-source CT and MRI. In this study, we compared the positive diagnostic rate and the diagnostic sensitivity of dual-source CT and MRI, as well as the image differences in two methods(including tophus, joint bone damage, articular cartilage damage, joint effusion, peripheral edema, synovial damage and urate crystal). The aim was to explore the value of dual-source CT and MRI in the diagnosis of patients with gouty arthritis. The results showed that the positive rate and diagnostic sensitivity of dual-source CT were higher than that of MRI, and the difference was statistically significant. Dual-source CT had a higher detection rate for tophus and bone destruction than MRI, and the difference was statistically significant. Dual-source CT has high specificity in detecting urate crystals. In examination of joint effusion, synovium and cartilage change, MRI has higher detection rates than dual-source CT, and the difference was statistically significant. The above results indicate that dual-source CT is specific in diagnosing urate crystals. The application value of dual-source CT in the diagnosis of gouty arthritis is higher than MRI.
