Recently, a novel MR thermometry has been demonstrated in vitro that is based on the application of exogenous PARAmagnetic Chemical Exchange Saturation Transfer (PARACEST) agents. By using this new technique, the inhomogeneous patterns of B1 deposition have been successfully detected for a phantom with 1 cm diameter that sits on the center of a 2 cm surface coil. Therefore, we believe that such technique may find important application, for example, in detection of hot spots in high field MRI diagnoses.
