This study presents a fast MR-thermometry sequence interleaved with a tunable SAR deposition module to simulate energy deposition of any clinically relevant MR-acquisition sequence. Validation of the method was performed on a 1.5T scanner using an MR-compatible catheter inserted into an agar-agar gel. Maximal temperature increase measured during equivalent SAR of a cardiac cine sequence was 41.8°C for a 90° flip angle. This sequence may help quantifying the maximal acceptable SAR for any patient wearing implanted device and/or for volumetric imaging of local heating in multi-transmit technology at high field.
