【摘要】 目的探讨MR诊断膝关节隐性骨折的临床价值。方法选取2013年1月—2015年3月重庆市黔江中心医院收治的膝关节隐性骨折患者32例,回顾性分析其X线和MR检查结果。结果 X线检查结果显示,32例患者均无明显骨折特征出现。而MR检查结果显示,32例患者均呈现骨折阳性,包括11例隐性皮质下骨折,9例隐性骨皮质骨折,12例隐形骨软骨骨折;在隐性骨折的受累区域表现为线状、网状或不规则状,且呈现低信号的T1WI序列,高信号的T2WI序列、高信号的STIR序列,低信号的骨折线。结论 MR诊断膝关节隐性骨折具有高敏感性、高安全性、操作简单、高诊断率、准确定位的特点,是诊断隐性骨折的首选方法。更多还原

【Abstract】 Objective To explore the clinical value of MR diagnosis on occult fracture of the knee. Methods A total of 32 patients with occult fracture of the knee were selected in Qianjiang Central Hospital of Chongqing from January 2013 to March 2015,and all of their X- ray and MR test result were retrospectively analyzed. Results X- ray test result showed no obvious fracture characteristics in 32 patients,while MR test result showed positive fracture in 32 patients,including 11 hidden cortical fractures,9 hidden cortical bone fracture,12 stealth osteochondral fracture. STIR sequence, the fracture line of low signal and MR occult fractures in the affected area of the performance of linear, mesh or irregular shape, and presented a sequence T1 WI,high signal sequence T2 WI low signal high signal. Conclusion MR diagnosis of occult fracture of the knee has a high sensitivity, high security, simple operation, high diagnostic yield, accurate positioning of features, and is the first choice for the diagnosis of occult fractures.更多还原
