Is it safe to wear metal during an MRI Scan?
An MRI or Magnetic resonance imaging is an imaging modern technique to obtain detailed organ and tissue images throughout the body. MRI does not use any x-rays or ionizing radiations. RF waves that interact with hydrogen atoms and strong external static magnetic fields are used in MRI to provide sharp images of the various organs and tissues. There is no limit on how many MRI scans a patient can have annually because, unlike x-ray and CT scans, MRI does not emit ionising radiation. Ionizing radiation is not produced by MRI. But it also has a significant flaw. It has two different effects on metals. The first has to do with the strong static field that surrounds us and exerts a magnetic pull on ferromagnetic elements like iron, steel, nickel, etc. A hazardous or even life-threatening force can be generated if the patient wears jewellery or has a pacemaker or other medical implant that has even a small amount of ferromagnetic contaminants. The magnetic force increases wi...
