Abstract
Magnetite particles and paramagnetic ion chelates are used as contrast agents in both nuclear magnetism logging of oilwells and in medical MRI. An analytic expression for reduction of T~2~ for free precession signal decay (or gradient echoes) by magnetite particles does not depend on diffusion and agrees with published Monte Carlo computations.
