| 目的 探讨高频超声在幼年特发性关节炎(JIA)膝关节病变中的诊断价值。方法 应用高频超声检查45例JIA活动期患者76个患侧膝关节和22例缓解期患者34个膝关节,观察二维声像图和彩色多普勒血流特征。结果 ①JIA活动期膝关节滑膜增厚显示率94.7%,髌上囊积液出现率89.5%,滑膜厚度与缓解期比较有显著性差异(P<0.01);②活动期滑膜厚度与关节积液的程度呈显著正相关(r=0.461);③增厚的滑膜内血流信号的显示率为31.9%,与滑膜厚度有关。结论 高频超声检查为幼年特发性关节炎提供可靠的诊断指标,是临床诊断JIA和评估疗效敏感、客观的检查方法。 |

| Objective To investigate the diagnostic value of high-frequency ultrasound on knee joint diseases of juvenile idiopathic arthritis (JIA). Methods Seventy-six knee joints in 45 patients with active JIA and 34 knee joints in 22 paracmasia patients were studied with high-frequency ultrasound and color Doppler flow imaging. Results ①The percentages of synovium thickness and suprapatellar bursa effusion of active JIA were 94.7% and 89.5%, synovium thickness showed statistically significant differences between active stage and paracmasia of JIA (P<0.01). ②A significant positive correlation was demonstrated between synovium thickness and suprapatellar bursa effusion (r=0.461). ③The detective rate of blood flow signals from hyperplastic vessels in the thickened synovium was 31.9%, it was due to synovial thickness. Conclusion The high-frequency ultrasound can provide reliable markers in judging JIA, for the deteermonation and monitoring of knee joint diseases of JIA. |
