【摘要】 目的探讨双源CT双能量成像在痛风尿酸盐结晶检测中应用价值。方法回顾性分析30例经临床确诊痛风患者和12例高尿酸血症患者的双能量CT表现。结果共30例痛风患者DECT发现尿酸盐结晶沉积,其中单关节受累17例,多关节受累13例,以指(趾)间关节及其周围软组织最明显;12例高血尿酸患者,DECT检查发现4例有尿酸盐结晶沉积。结论双源CT双能量成像技术具有简便、无创、快捷、灵敏、准确及可重复性强等优势,可以作为痛风诊断、疗效评估及痛风高危人群筛查的首选检查方法。更多还原

【Abstract】 Objective To investigate the application value of dual source dual energy CT in the detection of gout crystals. Methods The dual energy CT findings of 30 patients with gout and 12 patients with hyperuricemia were analyzed retrospectively. Results Uric acid crystal deposition was detected in30 patients with gout, including 17 cases of single joint involvement and 13 cases of multiple joints involvement. The interphalangeal joint and its surrounding soft tissue were the most obvious. There were 4 cases were found uric acid deposit by DECT in 12 patients with hyperuricemia. Conclusion Dual-source dual-energy CT has the advantages of simple, non-invasive, rapid, sensitive, accurate and repeatable. It can be used as the preferred method for diagnosis, evaluation of therapeutic effect and screening of high-risk gout population.更多还原
