There is no need to change clothes during the MRI examination. The requirement of the MRI is to clarify what metal-like objects are on the patient’s body before the examination, such as cell phones, bank cards, keys, metal belt buckles, or metal pendants on clothes and so on, which need to be removed in advance. It is also important to ask the patient’s medical history before the MRI to see if any metal-like implants have been placed in the body. If the patient has undergone surgery and has metal-like implants in his or her body, the MRI cannot be done and the doctor will ask the patient to choose another method of examination.
