It possible the area at which the doctor needs to see is not showing up well.
This most often is because you were not perfectly still. The slightest movement will cause distortion on those things.
Sometimes the techincian will think its ok, but once it gets in front of the skilled eye, its not good enough.
It's for your good. They don't want to miss anything.
I have had that problem happen to me and had to repeat.

Perhaps the tissues they are interested in didn't show up as clear, and the settings require refinement for the particular tissues in question? The magnetic field flips atoms, so frequency will change the response in different tissues.
You didn't mention what it was for, so they could even been looking for changes such as infection spread or response to treatments.
