Abstract
Red blood cells (RBC's) loaded with nonradioactive chromium in paramagnetic form are employed as a contrast agent for magnetic resonance imaging (MRI). The method has promise for intravascular imaging applications where the contrast agent must remain in the circulatory system. Specific uses of this kind include locating gastrointestinal bleeding, differentiation of tumor from edema, MRI angiography, and determination of tissue perfusion. The Cr-labelled RBC's can also be used for liver and/or spleen MRI examinations.
