Abstract : In this report, a case of fire in a positron emission tomography
(PET)/magnetic resonance (MR) imaging system
due to blanket combustion is discussed. Manufacturing
companies routinely use copper fibers for blanket fabrication,
and these fibers may remain within the blanket hem.
By folding a blanket with these copper fibers within an
MR imaging system, one can create an electrical current
loop with a major risk of local excessive heating, burn
injury, and fire. This hazard applies to all MR imaging
systems. Hybrid PET/MR imaging systems may be particularly
vulnerable to this situation, because blankets are
commonly used for fluorodeoxyglucose PET to maintain a
normal body temperature and to avoid fluorodeoxyglucose
uptake in brown adipose tissue.
