Discussion: I have prolonged Fibromyalgia pain, I asked my attending physician for an MRI, and he politely refused me, claiming there was no need.

MRI is a very reliable test but quite expensive. Fibromyalgia patients are usually not life-threatening, and surgical solutions are not an option, so those requesting an MRI will likely be required to pay for it out of pocket.

MRI imaging is a costly test relative to alternatives (CT, ultrasound, and the like). Doctors keep the MRI test for several more urgent conditions, including cancer patients, fear of cancerous tumors, complex surgeries, and life-threatening situations. This inevitably means that many patients are refused an MRI even with comprehensive health insurance. Some countries deliberately produce a shortage of MRI equipment to avoid the high financial outlay.
