Hi Marilyn!
That's an interesting comment you heard. I wonder who and/or what's behind it. If you read the research literature that is published by the research labs and universities who are on top of this, fibro still has no known cause. The idea of an auto-immune type of disorder has long been a good theory. Currently, information and scientific testing by places such as Stanford University Pain Centers are beginning to think it might come from the central nervous system but there still is nothing definitive.
My suggestion would be that if the cause isn't known then how could it be spotted and/or diagnosed from a brain MRI. It might be a but cynical of me but most often when unsubstantiated claims are made that it's one of two things. Either the person(doctor) has no idea and doesn't want to admit to it... OR... someone is selling something.
Below is a descript
ion of how fibromyalgia is diagnosed. This is from the National Institute of Health (NIH) and is concurrent with major medical research, at this time. Also, I put the link below if you are interested. Hope this helps you.

How Is Fibromyalgia Diagnosed?
Research shows that people with fibromyalgia typically see many doctors before receiving the diagnosis. One reason for this may be that pain and fatigue, the main symptoms of fibromyalgia, overlap with those of many other conditions. Therefore, doctors often have to rule out other potential causes of these symptoms before making a diagnosis of fibromyalgia. Another reason is that there are currently no diagnostic laboratory tests for fibromyalgia; standard laboratory tests fail to reveal a physiologic reason for pain. Because there is no generally accepted, objective test for fibromyalgia, some doctors unfortunately may conclude a patient’s pain is not real, or they may tell the patient there is little they can do.
A doctor familiar with fibromyalgia, however, can make a diagnosis based on criteria established by the American College of Rheumatology (ACR): a history of widespread pain lasting more than 3 months, and the presence of diffuse tenderness. Pain is considered to be widespread when it affects all four quadrants of the body, meaning it must be felt on both the left and right sides of the body as well as above and below the waist. ACR also has designated 18 sites on the body as possible tender points. To meet the strict criteria for a fibromyalgia diagnosis, a person must have 11 or more tender points, but often patients with fibromyalgia will not always be this tender, especially men (see illustration below). People who have fibromyalgia certainly may feel pain at other sites, too, but those 18 standard possible sites on the body are the criteria used for classification.
