Abstract (en)

[origin: CA2115582A1] 2115582 9303671 PCTABS00020 A method of magnetic resonance imaging (MRI) is disclosed which employs a diamagnetic contrast agent comprising gas-carrying, non-magnetic microparticles, which are preferably microspheres consisting of minute gas bubbles encapsulated by stabilized bicompatible material. The method is especially useful in imaging the vascular system as in angiography or venography.
