踝关节的磁共振成像技术与临床应用探讨

目的 探讨踝关节的磁共振成像技术与临床应用价值.方法 42例病例(男33例,女9例)应用矩形表面线圈(GPFLX线圈)作患侧踝关节的T2加权像扫描、T1加权像扫描、脂压T2加权像扫描.扫描范围包括踝关节的矢状位、冠状位、轴位.结果 优片率达到90%以上.42例中,创伤性关节炎及创伤性关节炎术后改变6例,踝关节挫伤14例,跟腱撕裂9例,其他软组织损伤6例,踝关节退行性变4例,未见异常3例.结论 踝关节的磁共振检查,可以较好地显示踝关节的损伤程度和范围,为临床提供了有价值的影像学资料.

MRI scanning technology for ankle joint and its clinical application

Objective To discuss magnetic resonance imaging(MRI)scanning technology for ankle joint and its clinical value.Methods 42 cases of ankle joint trauma were examined with MRI using GPFLX coil.It was performed through sagittal T2WI,T2WI F/S,T1WI;coronal T2WI;axial T2WI.FOV was big enough for the whole trauma ankle joint.To make image clear,some soft materials should be placed between the trauma ankle joint and the GPFLX coil.The injured ankle joint was not allowed to move.The technology of No Phase Wrap is also necessary.Results The high quality rate was up to 90% for the ankle joint.Among 42 cases,6 had traumatic arthritis,14 had ankle joint contusion,9 had Achilles tendon rupture,6 had other structural injuries,4 had late degenerative change,and 3 had normal images.Conclusion MRI is a sensitive technique for injured ankle joint.It can accurately show the degree and location of ankle joint trauma.It has an important clinical significance in finding bone contusion and other structural injuries,and it is very helpful for treatment.
