摘要：
Scan time in diffusion-relaxation magnetic resonance imaging ("MRI") is reduced by implementing time-division multiplexing ("TDM"). In general, time-shifted radio frequency ("RF") pulses are used to excite two or more imaging volumes. These RF pulses are applied to induce separate echoes for each slice. Diffusion MRI data can thus be acquired with different echo times, or alternatively with the same echo time, in significantly reduced overall scan time. Multidimensional correlations between diffusion and relaxation parameters can be estimated from the resulting data.
