Generally you cannot have a hip MRI with metal braces, if you have to do it, it is recommended to remove the metal braces first. Hip MRI is performed in the environment of strong magnetic field, due to the presence of strong magnetic field and resonance, metal braces belong to a kind of objects with magnetism, which will affect the uniformity of the magnetic field. This causes artifacts and distortions in the image, and may also produce thermal effects causing local tissue burns. At this point it is difficult to determine whether the artifacts are caused by the unevenness of the magnetic field due to the metal braces, or whether the patient has a lesion of his own. In addition, the metal braces may be displaced during the hip MRI and enter the body causing accidental damage to the body, and if inhaled into the machine, can cause damage to the machine. It is recommended that patients can go to the hospital stomatology department to remove the metal braces when doing hip MRI, and then wear them after the examination to avoid affecting the results of the examination and causing adverse consequences.
