title: The efficacy of paramagnetic ions on spin lattice relaxation time in biological systems.
abstract: This paper summarizes the observations of different studies concerning the influence of paramagnetic ions on spin-lattice relaxation times. Neither the comparison between different organs, different animals nor the comparison between different tissues (normal and malignant) showed correlation of practical consequences between the paramagnetic ion concentrations in whole tissues and spin-lattice relaxation times.
