[Unidimensional imaging. A simple method for evaluating the efficacy of a contrast agent in magnetic resonance imaging. Application of new nitroxides].
We present an experimental set-up of one-dimension imaging which permits on a conventional NMR spectrometer, to measure the difference in relaxation time T1 of two organ samples, one normal and the other injected with a contrast agent. Using that technique and M.R.I. two new nitroxides reveal a substantial contrast effect for kidneys and heart.
