B超在膝关节病变中的诊断意义

Diagnostic significance of color Doppler ultrasonography in knee arthrophy

目的评价B超对膝关节病变诊断的价值及临床意义。方法对34例68个膝关节病变包括骨关节炎或类风湿关节炎的患者进行B超检查,分析结果并与膝关节X线平片及磁共振(MR)作对照。结果在滑膜增厚、关节腔积液、软骨病变、软骨下骨质破坏、月国窝囊肿及半月板变性等方面,B超检查具有良好的分辨率,检出率分别为71%、72%、74%、43%、6%和16%,与X线对比两者差异有统计学意义(P<0.05),与MR比较,两者差异无统计学意义(P>0.05),但在关节间隙、骨赘形成及骨质疏松等反映骨性改变方面,不如X线及MR敏感。结论B超对于膝关节病变的诊断具有独特的价值及临床意义。

Objective To evaluate the value and clinical significance of color doppler uhrasonography in the diagnosis of knee arthropathy. Methods Both color Doppler ultrasonography and knee roentgenograph were used for detecting 34 cases with osteoarthritis or rheumatoid arthritis and the results were compared. Resuits In detecting the changes of synovial hypertrophy, arthroedema, knee cartilage affection, destruction of bone under cartilage, popliteal cyst and meniscus apomorphosis, the uhrasonography had higher resolution power than X-ray film. The detection rate of above changes by uhrasonography was 71%, 72%, 74%, 43%, 6% and 16% respectively. The difference between the detection rates of ultrasonography and X-ray was significant （P〈0.05）. Both ultrasonography and MR could discover changes of cartilage, synovial membrane, meniscus of knee joint well. The difference was not significant （P〉0.05）. Conclusion Color doppler ultrasonography is useful in the diagnosis of knee joint diseases.
