Magnetic resonance imaging, or MRI for short, is a type of noninvasive imaging procedure that lets a doctor view inside the body. A brain MRI scan may be recommended if a doctor suspects that a patient has some type of brain problem, such as a brain injury, brain tumor, recurrent headaches or cognitive deficits. Patients concerned about brain MRI side effects should consult a physician for further guidance and care.
No Side Effects
As of 2010, no significant side effects have been reported by patients who receive a brain MRI scan. This procedure does not expose the body to ionizing radiation, thereby limiting the risk of MRI side effects.
Skin Injury or Burns
Typically, a patient will be requested to remove all metal accessories or objects from their body prior to undergoing a brain MRI. Such metal objects can include earrings, watches, buttons, hair clips or bracelets. If these objects are not removed, a patient can sustain a skin injury at the site of the metallic object, the Better Health Channel notes. Certain patients may develop irritation or a burn where the metal object is located. Such side effects are rare and can be avoided by following a doctor's instructions before undergoing a brain MRI. Patients should let a doctor know if they have any implanted metal devices within the body, such as a pacemaker or bone pins. These patients typically should not receive a brain MRI, as the magnetic field produced by the MRI can damage these internal metal constructs.
Nephrogenic Systemic Fibrosis
Patients with kidney disease who undergo a brain MRI are at an increased risk of developing nephrogenic systemic fibrosis as a side effect, warn health professionals with RadiologyInfo.org. Though this condition is rare, nephrogenic systemic fibrosis can cause progressive hardening of the skin and decreased limb flexibility. Affected patients can have difficulty walking normally without assistance or may lose the ability to walk entirely over a span of a couple of weeks, according to the Global Fibrosis Foundation.
Allergic Reaction
Prior to having a brain MRI, patients are typically injected with a contrast dye, such as gadolinium. This dye helps the doctor differentiate the various components and structures within the brain. Rarely, patients can experience an allergic reaction to the MRI contrast dye, according to the University of Maryland Medical Center. The side effects of an allergic reaction can include difficulty breathing, skin hives and an increased heart rate. If such a reaction occurs during a brain MRI, the affected patient is generally treated immediately by on-site technicians or doctors.

I have had one of the worst migraines of my life after a brain MRI w/contrast. My doctor said that the dye could have been the trigger as I am prone to migraines. Anyone else have a similar side affect?
