Heat-activated liposomal MR contrast agent: initial in vivo results in rabbit liver and kidney.

abstract：:Diffusion magnetic resonance (MR) imaging is evolving into a potent tool in the examination of the central nervous system. Although it is often used for the detection of acute ischemia, evaluation of directionality in a diffusion measurement can be useful in white matter, which demonstrates strong diffusion anisotropy...
