Paramagnetic metalloporphyrins as potential contrast agents in NMR imaging
FEBS Letters
|March 12, 1984
Abstract:
Several water-soluble paramagnetic metalloporphyrins were found to increase significantly the relaxation rate (1/T1) of water. Such compounds are known to be selectively retained by tumors in animals, and consequently we identify them as potential contrast agents for tumors in NMR imaging.
