Does the MRI appearance of acute hamstring injury change significantly in the first 7 days?
MRI can be performed on any day during the first week following an acute hamstring muscle injury without significant changes in the appearance of oedema or tear detection.
We observed insignificant day-to-day changes in the extent of oedema throughout the first week following acute hamstring injury. Fibre disruption (tear) was detectable from the first day after injury. These findings indicate that MRI can be performed on any day during the first week following an acute (hamstring) muscle injury.
