超声诊断手部小关节滑膜炎的临床应用

Clinical Application of Ultrasonic Diagnosis of Articular Synovitis in Hand

目的：探讨超声检查在小关节滑膜炎诊断中的应用价值。方法：用7-18 MHz高分辨率超声对20例类风湿性关节炎患者的腕关节,掌指关节及近端指间关节均行双侧对比扫描检查,观察小关节滑膜病变声像图及血流特点。结果：共检查600个关节,检出关节腔积液489个,检出率81.5%,关节滑膜增厚398个,检出率66.3%,关节内血管过度增生87个,检出率14.5%。结论：高分辨率超声是早期诊断手部小关节滑膜炎简便易行且安全有效的检查方法。

Objective： To confirm the value of early diagnosis in the rheumatoid arthritis using high resolution frguency ultrasonography and Doppler ultrasound. Methods： 7- 18 MHz high resolution ultrasound probe was used in 20 patients with rheumatoid arthritis. The joints of wrist, metacarpophalangeal and proximal interphalangeal joints were detected, and the ultrasonographic characteristics and blood flows in the joints were checked with HFUS. Results： 489 articular cavity fluid were detected, and total rate was 81.5%, 398 were detected thickening of the synovialmembrane, total detection rate was 66.3%, detected 87 joints within thevascular overgrowth, with a total detection rate of 14.5%. Conclusion： High-resolution ultrasound is an easy, safe and effective method for early diagnosis of synovitis in small hand joint in rheumatoid arthritis.
