Which option is acceptable for reducing a proximity burn in MRI procedures?

To reduce the risk of proximity burns during MRI procedures, the use of appropriate thickness in padding is critical. A pad that is 1cm thick provides sufficient insulation between the patient's skin and the MRI equipment, which helps to dissipate heat generated from the surface of the coil or other magnetic components. The thickness of 1cm helps ensure better thermal regulation, minimizing the potential for burns in sensitive areas.

Options that involve thinner materials, such as a 1mm thick pad or a towel at 1cm thick, may not provide adequate thermal insulation. A towel may also not be as effective in distributing pressure or heat as a proper pad designed for MRI use. Therefore, the choice of a 1cm thick pad is superior in mitigating the risk of burns and optimizing patient safety during the imaging process.
