高频超声与双能量CT联合诊断早期痛风性关节炎的价值

The value of high-frequency ultrasound combined with dual-energy CT in the diagnosis of early gouty arthritis

目的 探讨高频超声与双能量CT单独诊断及联合诊断早期痛风性关节炎的价值.方法 分别对50例病程<3个月的痛风性关节炎患者行高频超声与双能量CT检查,分析高频超声诊断早期痛风性关节炎的声像图特征,比较二者的诊断效能,探讨联合诊断早期痛风性关节炎的价值.结果 高频超声对晶体沉积的检出率高于双能量CT (P<0.05).早期痛风性关节炎晶体沉积的超声表现以点状高回声最常见,其发生率高于云雾状高回声和“双轨征”(P<0.05).将高频超声与双能量CT二者联合应用诊断早期痛风性关节炎,优于任何单一检查(P<0.05).结论 高频超声对早期痛风性关节炎诊断较双能量CT更为敏感,两种方法联合诊断可提高诊断效能.

Objective To explore the value of high-frequency ultrasound combined with dual-energy CT in the diagnosis of early gouty arthritis.Methods High-frequency ultrasound and dual-energy CT were performed on 50 patients with gouty ar-thritis whose course of disease were less than 3 months.The sonographic characteristics of high-frequency ultrasound in the di-agnosis of early gouty arthritis were analyzed.The diagnostic efficiency of high-frequency ultrasound and dual-energy CT were compared,and the value of the two methods combined diagnosis of early gouty arthritis was discussed.Results The detection rate of high-frequency ultrasound was higher than that of dual-energy CT(P<0.05).In the early stage of gouty arthritis,the most common ultrasonic manifestations of crystal deposition were pointhigh-echo,which was more than cloud high-echo and“double track sign”(P<0.05).The combination of high-frequency ultrasound and dual energy CT was superior to any single examination in the diagnosis of early gouty arthritis(P<0.05).Conclusion High-frequency ultrasound is more sensitive than dual-energy CT in the diagnosis of early gouty arthritis.The combination of two diagnostic techniques can improve the diagnosis efficiency.
