1. A method for NMR imaging the blood vessels of a patient which comprises administering, as a contrast agent, a cascade polymer complex having a size sufficiently large for its retention in the blood vessels for a time sufficient to provide contrast in NMR imaging but sufficiently small for physiologically acceptable excretion and having sufficient loading of paramagnetic atoms chelated by macrocyclic complex-forming ligands to achieve blood pool imaging by NMR.
