ABSTRACT:
A method of magnetic resonance imaging (MRI) is disclosed which employs a diamagnetic contrast agent comprising gas-carrying, microparticles, which are preferably microspheres consisting of minute gas bubbles encapsulated by stabilized biocompatible material. The MRI is carried out to produce a shortened T2* effect. The method is especially useful in imaging the vascular system as in angiography or venography.
