The feasibility of human head imaging at 14T is explored using a Bloch-based MRI simulator that considers realistic B0, B1, and E1 distributions, including multiple transmit and receive channels. Field inhomogeneity, image SNR and SAR in the human head with and without RF shimming are examined at 3T, 7T, and 14T. The results showed a dramatic increase of image SNR from 3T to 14T, with a more subtle SAR increase, especially from 7T to 14T
