Prediction of the RF burning that may occur during an MRI examination is one of the key issues in MR safety. Although several methods have been developed for mapping the specific absorption rate (SAR), few practical methods for predicting RF burning have been demonstrated because of the difficulty in actualizing RF burning in a phantom study. In this study, we developed a method of mapping high-SAR areas using a low-RF power scan and demonstrated the prediction of RF burning in a phantom study using an elaborate setup of an RF resonant loop.
