What precaution should patients take before undergoing an MRI?

Before undergoing an MRI, it is crucial for patients to remove all metallic objects. This precaution is necessary because MRI machines use powerful magnets, and any metallic items can interfere with the imaging process or pose a risk of injury. Metals can distort the magnetic field, leading to inaccurate images and potentially damaging both the equipment and the items themselves. Additionally, there is a risk of projectiles if ferromagnetic objects are present, as they may be pulled into the MRI scanner.

Removing items such as jewelry, watches, eyeglasses, and hairpins ensures patient safety and allows for the most accurate imaging results. Patients should discuss with the technologist any implants or devices they may have, as some might also be contraindicated for MRI.
