摘 要: | 目的比较X线和双能源CT对痛风性关节炎的诊断价值。方法回顾性分析96例痛风性关节炎患者共186个患病关节的X线和DECT影像表现,采用卡方检验对比分析2种检查方法的检出率及对不同病变的显示率。结果 X线和DECT检查的检出率分别为52.69%(98/186)和86.56%(160/186),DECT高于X线,两者比较差异有统计学意义(χ~2=33.56,P0.005)。X线未见显示关节积液和尿酸盐结晶,X线显示痛风结节、软组织肿胀和骨质破坏关节个数少于DECT(χ~2=45.06,P0.005;χ~2=72.44,P0.005;χ~2=11.27,P0.005),差异具有统计学意义。结论 DECT较X线对痛风性关节炎有更好的诊断价值,DECT对尿酸盐结晶具有较高的特异性。

Abstract: | 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 chi-square 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. |
