Anti-Microbial fabric

In July 2014, Global News shared a story titled as ' Why some clothes could pose a safety hazard during MRI exams,' following an incident at an MRI (Magnetic Resonance Imaging) facility in Canada.

Due to the magnets used for the imaging, facilities state no metal is allowed to be on an individual walking into the room of an MRI. The MRI Technologist typically checks before starting the MRI. But this incident tells of women wearing Yoga pants and experiencing discomfort a few minutes into the MRI and needing to have the MRI stopped. Unsure of the reason for discomfort chose to take the pants off and finish the MRI with no further issue. Later it was determined to be silver fibers in the pants.

Some fabric includes silver or metal fibers, included on clothing labeled as Anti-Microbial. But for caution because of this incident, more hospitals no longer allow the use of personal clothing during scans and require the use of gowns or other hospital clothing.

Metal in clothins is common in undergarments but also possible in pants.
