Temperature mapping in presence of respiratory motion can accommodate intra-scan motion using fast 2D-EPI sequence but inter-scan motion remains a challenge during free-breathing acquisition. To address this limitation, we evaluated, in vitro on a mobile gel, a 2D simultaneous multi-slice EPI sequence with a slice acceleration factor up to 3 during radiofrequency ablation. Inter-scan motion and temperature elevation measured with accelerated sequences are compared to reference values using a non-accelerated sequence. Additionally, evidence or absence of potential false-positive heating are considered.
