MRI scanning technology for ankle joint and its clinical application / 解放军医学杂志

ABSTRACT

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.
