摘要：

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 T2 for free precession signal decay (or gradient echoes) by magnetite particles does not depend on diffusion and agrees with published Monte Carlo computations.
