Real-time magnetic resonance imaging of laser heat deposition in tissue

Magn Reson Med. 1991 Sep;21(1):132-7. doi: 10.1002/mrm.1910210116.


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 2s, clearly showed the dynamics of temperature-related signal intensity changes in the regions irradiated by the laser.
