The MRI is a more sensitive test than the ultrasound or CT scan, it may be possible that due to this enhanced detail what was thought to be a lesion, really isn't. I cannot comment on what the lesion is without reviewing the report - the possibilities should be in the radiologist's impression.
If there is indeed a lesion in the liver, the biopsy would be the more comprehensive test to find out what it is. There are some cases where the characteristics on the imaging study can suggest diagnoses.
I would discuss these options with your personal physician.
