摘要
目的探讨X线和双能量CT(DECT)在痛风性关节炎(GA)中的诊断价值。方法对30例GA患者的患病关节分别进行X线、DECT检查,比较两种方法对患病关节检查的阳性率,观察关节尿酸盐结晶、痛风石、骨质破坏、软组织肿胀和关节积液情况,并对比两种检查方法对以上关节炎损害病变征象的检出率,同时比较DECT显示的尿酸盐沉积部位与临床评估的差异。结果 X线和DECT检查的检出率分别为52.42%(65/124)和86.29%(107/124),DECT的检出率高于X线(P<0.05);X线显示痛风石、骨质破坏及软组织肿胀的关节个数少于DECT(P<0.05),且X线不能显示关节积液和尿酸盐沉积。所有GA患者共发现229处尿酸盐沉积。结论 DECT较X线对痛风性关节炎有更好的诊断价值,DECT可以检测出GA患者尿酸盐结晶沉积,包括一些亚临床部位,可为一种无创、简便的检查方法,对GA有较重要的鉴别诊断意义。
Objective To compare the value of X- ray and DECT in diagnosis of gouty arthritis( GA). Methods The images of X- ray and DECT were selected in 30 patients with gouty arthritis. And compared the inspection positive rate of two methods; and observed the bone urate crystals,gout stone,bone destruction,soft tissue swelling and joint effusion,and comparing lesion detection rate above signs of arthritis damage in two methods. Then compared urate deposition site in DECT and evaluated clinical value. Results The diagnostic positive rate of X- ray and DECT were respectively 52. 42%( 65 /124) and 86. 29%( 107 /124). DECT was superior to X-ray( P < 0. 05). X- ray was inferior to DECT in finding gout stone,bone destruction,soft tissue swelling( P < 0. 05). And X- ray did not show joint effusion and urate crystals. 229 urate crystals were found in DECT. Conclusion The diagnosis of DECT is superior to X-ray in GA,and DECT could detect urate crystals in GA patients,and including some sub- clinical site,and to be a noninvasive and simple method. It has the important significance in differential diagnosis in GA.
