If the MRI is a flat-scan MRI, you can eat breakfast. Since the MRI takes a long time, it is best not to eat if the patient’s gastrointestinal tract is not functioning well. If the patient eats and then experiences gastrointestinal discomfort during the procedure, it may affect the results of the MRI images and may even require the MRI to be redone. Enhanced magnetic resonance generally need to empty stomach, because to do enhanced magnetic resonance need to inject contrast agent into the vein, some patients will have nausea, vomiting and other gastrointestinal reactions after inputting the contrast agent, eating breakfast may aggravate this gastrointestinal reaction, so to do the enhanced magnetic resonance all need to empty stomach.
