B超与MRI诊断髋关节一过性滑膜炎的价值比较

Diagnostic Value of B Ultrasound and MRI in Transient Synovitis of the Hip

目的探讨B超和MRI用于髋关节一过性滑膜炎的检出率，并分析原因。方法回顾性分析2014年2月～2015年8月我科接诊的髋关节一过性滑膜炎患者52例（66髋），分别行B超和MRI检查，对比其检查阳性率。结果52例患者中1周内由B超确诊一过性滑膜炎37例，MRI确诊44例，其诊断阳性率分别为71．17％（37／52）和84．62％（44／52）。1周以上患者中，MRI诊断阳性率为13．61％（7／52），高于B超9．62％（5／52）；总阳性率MRI高于B超，其差异均有统计学意义（P〈0．05）。结论在髋关节一过性滑膜炎的早期影像诊断方法中，MRI有较高的敏感性和特异性，可较好显示骨质细微信号改变，具有临床应用前景。

Objective To investigate detection rates of B ultrasound and MRI in transient synovitis of the hip and analyze the reasons. Methods 52 patients （66 hips） with transient synovitis of the hip were analyzed retrospec- tively from Feb. 2014 to Aug. 2015. B ultrasound and MRI were performed and positive rates were compared. Results 37 patients were diagnosed by B ultrasound, and 44 were diagnosed by MRL Diagnostic positive rates were 71.17% （37/52） and 84.62% （44/52） respectively. The positive rate of MRI was 13.61% （7/52）, which was higher than 9.62% （5/52）by B ultrasound in patients sick for more than one week. The total positive rate of MRI was higher than that of B ultrasound（ P 〈 0.05 ）. Conclusion MRI has high sensitivity and specificity in the early imaging diagnosis of transient synovitis of the hip, which shows fine bone signal change and has a wide prospect of clinical application.
