目的:探讨高频超声在类风湿关节炎(RA)患者双手关节病变的应用价值。方法:高频超声、X线检查108例活动期RA的腕关节和12例临床缓解期RA的腕、掌指、近端指间关节,分析其影像学特征。结果:108例活动期RA按病程分为两组,检查216个腕关节。病程<1年组的患者骨侵蚀及腱鞘病变显著低于病程≥1年组(P<0.01)。病程<1年组超声发现骨侵蚀率明显高于X线(P<0.05)。而病程≥1年组超声发现骨侵蚀率低于X线,差异无统计学意义(P>0.05)。12例临床缓解期RA共检查264个关节,超声发现滑膜炎的阳性率明显高于体格检查(P<0.05)。结论:RA疾病早期高频超声发现骨侵蚀优于X线;临床缓解期超声发现滑膜炎的敏感性高于体格检查。
Objective: To investigate the value of high frequency ultrasound in the treatment of bilateral joint disease in patients with rheumatoid arthritis (RA). Methods: High-frequency ultrasound and X-ray were used to examine the radiographic features of the wrist, metacarpophalangeal and proximal interphalangeal joints of 108 active RA patients and 12 RA patients. Results: 108 cases of active RA were divided into two groups according to the course of the disease, 216 wrist joints were examined. Patients with duration <1 year had significantly lower rates of bone erosion and tendon sheath lesions than those with durations ≥ 1 year (P <0.01). Course of disease <1 year group found that bone erosion rate was significantly higher than X ray (P <0.05). The duration of disease ≥ 1 year group was lower than the bone erosion rate of X-ray, the difference was not statistically significant (P> 0.05). In the 12 cases of clinical remission, 264 joints were examined, and the positive rate of synovitis was significantly higher than that of physical examination (P <0.05). Conclusions: The early echocardiography of RA is superior to X-ray in the early stage of RA disease. The sensitivity of synovitis in clinical remission is higher than that of physical examination.
