We applied diffusion‐sensitive echo planar (Instascan) imaging to study thermal changes caused by a Nd:YAG laser. Images of phantom materials and normal rabbit brain tissue in vivo , acquired in 150 ms, every 2 s, clearly showed the dynamics of temperature‐related signal intensity changes in the regions irradiated by the laser. © 1991 Academic Press, Inc.
