Abstract
Magnetic Resonance Image (MRI) has been used as a safe, conventional and harmless diagnostic tool. However, thermal injuries have frequently been reported during MRI scanning due to the heat generated by the reaction with the magnetic field. It is recommended that metal-containing monitoring devices such as pulse oximetry and ECG monitoring leads should be removed prior to the start of the MRI scan, but these monitoring devices are inevitably placed in children or patients in the intensive care unit who have low compliance with the scan. Since the interaction between the metal probe or wire loop of pulse oximetry and the magnetic field can result in high thermal conduction, full-thickness burn can occur over the entire body surface during the MRI examination. Several cases of thermal burns from pulse oximetry on the fingers have been reported. However, we present a case of a full-thickness burn arising left earlobe in a 2-month-old child caused by the high conduction heat from pulse oximetry metal probe.
