What is the standard patient preparation for a magnetic resonance imaging (MRI) scan?

The standard patient preparation for a magnetic resonance imaging (MRI) scan emphasizes the importance of safety, particularly regarding the presence of metallic objects. MRI uses strong magnetic fields and radiofrequency energy, and metallic items can interfere with the imaging process or pose serious safety risks, such as being pulled into the magnet or causing burns. Therefore, patients are instructed to remove all metallic objects, including jewelry, watches, hairpins, clothing with metallic fasteners, and any other items made of metal before undergoing the scan.

While hydration and appropriate clothing may also be considerations in specific circumstances, the primary and critical aspect of preparing a patient for an MRI scan is ensuring there are no metallic objects present. This is essential for both the patient's safety and the accuracy of the imaging results.
