Recent
work reported spatially related errors in temperature maps and TD during
power application, while using 2D GRE-EPI PRFS imaging with orthogonal
interleaved slices (1). We demonstrate that RFA induced cavitation’s
effects are the primary source of errors in PRFS imaging using truly
simultaneous ultrasonography and MRI.
