I had a Lumbar MRI scan 2 years ago, and wanted a copy of the report today due to having some more back pain. In reading the report , it said many things, such as spurs, disc protrusions, and one thing it said was, Heterogeneity of the marrow for which a hematopoietic variant is favored, which can be seen with increased frequency with anemia, smoking, or obesity and for which clinical correlation, laboratory correlation and / or follow up imaging would be of value in confirming benign etiology. My doctor never mentioned this, only my spurs, disc, and stress fractures. Is this anything to worry about???
