The risks that many people are exposing themselves to by undergoing a magnetic resonance imaging (MRI) scan are alarming technicians, especially with the new vogue of MRI guided surgery. People with implanted devices including vagal nerve stimulators, cochlear implants, and cardiac pacemakers and defibrillators are warned prior to scanning with MRI as the magnets can upset these sophisticated, in some cases, life saving instrument. The increasing girth of the population is also causing logistics difficulties, with many obese people too large to fit through the scanner. MRIs offer detailed images of the body without costing the patient high doses of radiation. However, the magnetic field can provide problems with deaths and injuries reported to be caused by flying metal objects coming towards an MRI machine with a person it, the interruption of implanted apparatus and burns from touching the sides of the machine. MRI technicians are therefore impressed upon regularly to check people for forgotten metallic objects on their person.
