Sorry to hear your daughter is suffering with migraines. Unfortunately we are not Doctors here, and it would not be right for any of us here to express an opinion on the MRI detail that you gave as we are not qualified.
Please try not to worry, we will support you and your daughter as best we can, but the best person to speak to about this is your daughters Consultant.
Please let us know how you get on, take care
