Translational molecular self-diffusion in magnetic resonance imaging. I. Effects on observed spin-spin relaxation.
Invest Radiol. 1984 Nov-Dec; (6): 484-90
The reduced T2 (spin-spin) relaxation times (T2obs less than 200 ms) measured on pure fluids on our 0.35T magnetic resonance imagers stimulated an investigation into this phenomenon. The cause for the short T2obs of fluids was found to be translational molecular self-diffusion of hydrogen nuclei through the pulsed slice-selective magnetic gradient in the imagers. Similar reductions in biological tissue T2obs were also attributed to molecular self-diffusion.
