Wearing a mask is very important as we all try to reduce the risk of Covid transmission.
The FDA recently issued a warning based on a case of facial burns associated with a mask during an MRI (Magnetic resonance imaging) procedure. As a result, one should carefully consider what type of mask one wears if you need to obtain an MRI. Masks with metal or antimicrobial coating containing metal should be avoided during an MRI procedure.
