摘要
目的探讨膝关节隐匿性骨折的MRI表现特点,评价MRI检查的诊断价值。方法常规X线片检查骨质未见明显异常患者45例,膝关节外伤一周内行MRI检查,检查序列包括T1WI、T2WI和STIR。结果45例中共53处膝部隐匿性骨折。T1WI呈不规则、边缘模糊的片状低信号,T2WI呈略高信号,STIR呈明显高信号,可伴有线样异常信号。常伴有韧带等软组织损伤。结论MRI是检查膝关节隐匿性骨折的最佳影像学方法,可减少或避免误诊和漏诊。
Objective To explore the value of MR imaging in the diagnosis of occult fracture of the knee joint. Methods Forty-five patients, who experienced knee traumas with obvious clinical symptoms and negative radiographic findings, had MRI examinations in a week. Results A total of 53 occult fractures of the knee joint were detected in the 45 patients. The Fracture imaging showed hypo-intensity on T1WI, slightly high intensity on T2WI, and marked hyperintensity on STIR, with ligament and soft tissue injuries and with linear abnormal signal intensity. Conclusion MRI is the best method in the diagnosis of occult fracture of the knee joint,which can avoid the misdiagnosis and missed diagnosis of occult fractures in the knee joint to a great extent.
