目的:探讨MRI对膝关节损伤的诊断及临床应用价值。
方法:回顾性分析266例膝关节损伤的MRI资料,男182例,女84例,年龄16～56岁,平均38岁。其中车祸损伤144例,运动损伤68例,其他54例。损伤类型,骨折31例,骨挫伤106例,软骨骨折11例,半月板损伤224例,韧带损伤198例,关节积液212例。
结果:31例骨折表现为线状长T1长T2信号影;106例骨挫伤表现为斑片状等或长T1WI、等或长T2WI信号,STIR序列呈高信号,边界不清;11例软骨骨折表现为软骨信号连续中断或凹陷,出现异常信号;224例半月板损伤表现为半月板低信号影内出现不同形状高信号灶;198例韧带损伤表现为韧带增厚、扭曲,韧带移行区有长T2信号和(或)短T1信号;212例关节积液表现为长T1长T2信号,血肿可见短T1高信号。
结论：MRI对膝关节损伤的诊断具有重要的临床价值。 |

Abstract:
Objective: To explore the evaluation of MRI in the diagnosis of the knee injury,and its clinical value.
Methods:To retrospectively analyse MRI pictures for clinical manifestations of 266 patients with knee injury.Age 16～56,in average of 38.The male 182 cases,the female 84 cases.The causes of the injuries were traffic accidents for 144 cases,atheletic damages 68 cases and another 54 cases.There were fractures in 31 cases,bone contusions in 106 cases,cartilage fractures in 11 cases,meniscus injury in 224 cases,ligament injury in 198 cases,joint hydrocele in 212 cases.Joint hydrocele showed signal of long T1 and T2.
Results:Thirty-one cases of bone fracture showed discontinuous,displayed long T1 and T2,one hundred and six cases of bone contusion showed low signals on T1WI and high signals on T2WI.Eleven cases of cartilage fracture showed discontinuous or umboilicate,and occurred normal signals,two hundred and twenty-four cases of meniscus injury in different shape,high signals in triangle and low signals.One hundred ninety-eight cases of ligament injury showed hypointense string thickening and marginal haziness or ware-line by MRI.Two hundreds and twelve cases of hydrarthrosis represented the signal of long T1 and T2,and the hematoma could see the short T1 high signal.
Conclusion:MRI can play important clinical value in diagnosis of the knee injury. |
