RF burn injuries occasionally occur at the contact points of skin and the bore wall, albeit out of common belief of hazardous loop forming. To investigate the mechanism of the RF burn injury occurred by the bore wall contact, we modeled an elbow-bore wall contact case on an electromagnetic analysis software by using the computable human phantom. The simulated SAR at the contact point varied up to 480% depending on the patient position in a scanner. This tendency was in accordance with the simulated electric field distribution in the scanner which is dominantly determined by the RF transmission coil.
