The general cost of an MRI of the ankle will cost about$800, which is more related to the local economy and the level of the hospital, but of course the fluctuation is usually not very large and may be about$200. The ankle MRI can find out if there is any significant fluid in the ankle joint, or if there is inflammation, or if there are other tumor lesions. The MRI of the ankle usually takes about 30 minutes. In addition, it is generally not suitable for patients who already have metal in their bodies. If there is metal that is a contraindication to MRI, the appropriate treatment will be done according to the test results. In addition, if you want to know whether there are obvious lesions in the ankle, you can choose CT and 3D reconstruction of the ankle, while MRI of the ankle is mainly to understand the soft tissue condition.
