What you can’t eat for an MRI depends on the specific part of the patient’s body that is being examined, as many parts of the body have no requirements for the type of diet. For example, for cranial, thoracic, pelvic, bone and joint system, and soft tissue exams, diet or lack of diet and type of diet do not have any effect on the exam. If the patient is doing a digestive system examination, such as liver, spleen, gallbladder, pancreas, gastrointestinal tract, etc., no matter what kind of food should not be eaten, because the gastrointestinal peristalsis after eating and drinking will form artifacts on the examination, which will affect the final diagnosis. Moreover, the gallbladder will contract and become smaller after eating, which is very unfavorable to the display of gallbladder disease, so before the MRI examination of the digestive system, patients are generally required to have a strict fasting, fasting and water.
