【摘要】：目的探讨双源CT双能量成像技术诊断痛风患者尿酸盐结晶的临床价值。方法选取2016年6—12月丽水市中心医院疑似痛风患者120例,按照国际公认美国风湿病学会(ACR)的痛风分类标准将其分为痛风组(n=75)和非痛风组(n=45)。两组均进行双源CT双能量成像技术检查,观察两组尿酸盐结晶阳性率;并分析双源CT双能量成像技术的灵敏度、特异度和准确率。结果痛风组尿酸盐结晶阳性率高于非痛风组(P0.05);75例痛风患者中,尿酸盐沉积于双手腕关节34例(45.3%)、双足踝关节26例(34.7%)、双足15例(20.0%)。双源CT双能量成像技术诊断痛风患者尿酸盐沉积的灵敏度为93.3%,特异度为94.7%,准确率为96.0%。结论双源CT双能量成像技术能准确诊断出尿酸盐沉积部位,可作为痛风病筛查的辅助手段。
[Abstract]:Objective to evaluate the clinical value of dual source CT dual energy imaging in the diagnosis of uric acid crystallization in patients with gout. Methods 120 suspected gout patients in Lishui Central Hospital from June to December 2016 were divided into gout group (n = 75) and non-gout group (n = 45) according to the internationally recognized American Society of Rheumatology (ACR) classification criteria. Dual-source CT dual-energy imaging was performed in both groups to observe the positive rate of uric acid crystal, and the sensitivity, specificity and accuracy of dual-source CT dual-energy imaging were analyzed. Results the positive rate of uric acid crystallization in gout group was higher than that in non-gout group (P 0.05). In 75 cases of gout, uric acid was deposited in the wrist joint of both hands in 34 cases, in the ankle joint in 26 cases, and in 15 cases in both feet. The sensitivity, specificity and accuracy of dual-source CT dual-energy imaging in the diagnosis of uric acid deposition in gout patients were 93.33,94.7g and 96.0g respectively. Conclusion Dual-source CT dual-energy imaging can accurately diagnose the deposition of uric acid, and can be used as an auxiliary method for gout screening.
