摘要
目的:应用超声与MRI对照分析,评估超声诊断半月板损伤的优势与不足。方法:选择经MRI检查诊断为半月板损伤的32例患者(40个病灶)作为研究对象;同时随机选取不同年龄、不同性别的60例(120个正常膝关节)行超声检查作为对照。结果:①超声检查可以提示半月板损伤的部位、范围。②半月板损伤区域的声像图可以是低回声、强回声,或局限不均匀区。③本组40个损伤部位,超声显示31个病灶,与MRI及手术对照基本符合,总符合率达77.5%。结论:超声在体表检查半月板声窗窄小,诊断半月板损伤虽不能提高诊断准确率,但有较高的符合率,并具有方便快捷、廉价、可双侧对比检查及评价关节动力学的优势,可作为膝关节损伤的首选筛查手段。
Objective： To evaluate the ultrasound in diagnosis of meniscus injury, by comparing with MR imaging. Methods： Ninety-two patients who underwent ultrasound for the evaluation of meniscus were studied. These patients were divided into two groups,one study group of 32 patients （40 lesions） who also had performed MRI before ultrasound examination, and one control group of 60 persons （120 healthy menisci） with different ages and sexes. Results：① Ultrasound could demonstrate the position and range of the menisci injury; ② On ultrasound, the menisci injury appeared as hyperechoic, hypoechoic or limited asymmetric area;③Thirty-one of forty menisci injury positions were displayed by ultrasound and the accuracy was 77. 5% （31/40）, which was basically accorded with MRI and surgical operation results. Conclusion： Although ultrasound did not im- prove the diagnostic accuracy of menisci injury limited by a small field of view, most of the pathological changes could be checked out and the accuracy was relatively high. Advantages of ultrasound include easy availability, economic, as well as easily compared with contralateral side. Ultrasound could be the preferred inspection method for diagnosis of meniscus injury.
