PDFAbstract
Obiective Compare the diagnosis value of X-ray and DECT imaging in gouty arthritis. Methods A retrospective study was performed in 186 symptomic joint of 96 patients with gouty arthritis. The images of X-ray and DECT were collected. The chisquare test was used to compare the diagnostic ability of X-ray and DECT. Results The diagnostic positive rate of X-ray and DECT were respectively 52.69%(98/186) and 86.56(160/186). DECT was superior to X-ray (χ2 =45.65,P<0.005). And X-ray did not show joint effusion and urate crystals. X-ray was inferior to DECT in finding gout node, soft tissue swelling and bone destruction(χ2 =45.06, P<0.005,χ2 =72.44, P<0.005, χ2 = 11.27, P<0.005). And There was significant difference. Conclusion The diagnosis of DECT is superior X-ray in GA, and DECT is characterized by specificity of urate crystals.
