1、双源CT对痛风性关节炎早期诊断的价值［摘要］目的探讨双源CT对痛风性关节炎早期诊断的价值。方法选取2015年1月〜2016年1月我院收治的临床疑似痛风患者227例，其中108例足踝部疼痛，63例手部疼痛，56例膝关节处疼痛，分别对这三组痛风患者进行双源CT扫描，以美国风湿病学会(ACR)的分类标准作为痛风诊断的“金标准”，通过对图片进行分析详细记录三组的扫描结果，对其所有数据及特异度和灵敏度进行统计学分析。结果108例双侧足部及踝关节疼痛患者中，确诊96例，双源CT诊断的准确度为95.37%,特异度75.00%,灵敏度97.92%；63例双侧手部及腕关节疼痛患者中，确诊痛风50例，双源CT诊断
2、的准确度为88.89%,特异度61.54%,灵敏度96.00%；在56例膝关节处疼痛的患者中，确诊46例，双源CT诊断的准确度为89.28%,特异度80.00%,灵敏度91.30%。结论双源CT作为现在临床上一种诊断痛风性关节炎的主要方法之一，具有无创性和可重复性，对提高痛风的诊断率有积极意义，且安全性更高，值得临床推广应用。［关键词］双源CT;痛风性关节炎；早期诊断；价值分类号］R445.3［文献标识码］A［文章编号］1674-4721(2016)06(a)-0119-03[Abstract]ObjectiveToexploreearlydiagnosticvalueofdual-sourc
