I have bad breath and these are the results of the mri. What does this mean and what can I do?

See your dentist. Rule out any dental problems, and then see your physician for guidance as to how to treat your condition.
Halitosis. If you are asking if an MRI caused you to have bad breath, the answer us no. Sometimes when a cat-scan is taken, you are made to drink "contrast" or given an IV infusion. These could alter your breath for a short period if time. This should go away in hours, not days or weeks.
