Ultrasonic surgery was performed in rabbits and dogs under the guidance of magnetic resonance (MR) imaging. Two different MR techniques were used to guide the ultrasound beam. T2-weighted images showed lesion formation within a few minutes after sonication. T1-weighted GRASS (gradient-recalled acquisition in the steady state) images were sensitive to temperature elevations, permitting monitoring of lesion creation with MR imaging. Short TR T1-weighted GRASS images were not as helpful in detecting temperature elevation because of a reduction in signal-to-noise ratio. T2-weighted fast spin-echo images were compared with conventional T2-weighted spin-echo images. The former produced high-quality images in a fraction of the imaging time. This study shows that it is possible to monitor and guide ultrasonic surgery with MR imaging.
