Mre

Has anyone heard of or had an MRE. I saw it on a news report it is an MRI but they put a piece of equipment over your liver area to detect what stage you are in your disease. There are no risk or side effects with this. My GI has not done a biopsy as he feels there are too many risk. I am going to ask him about this MRE I would like to know what stage I am at with this disease.
