Single-shot EPI images of a sample of PEG 400 (polyethylene glycol, mol. wt.ave = 400 g/mol) contained within a 5 cc syringe. In addition to the PEG 400 liquid, the lumen of the syringe contains the ×-shaped piston taken from another identical 5 cc syringe. Both images were acquired at 4.7 T with system #2 (after proper eddy-current compensation) from a 2-mm thick slice with a 14 × 14 mm2 (64 × 64) field-of-view using a spin-echo preparation (TE = 97 ms). Left. Image acquired without diffusion weighting (b = 0). Right. Heavily diffusion-weighted (b = 534,000 s/mm2) image of the sample employing a pair of trapezoidal gradient pulses on either side of the spin-echo refocusing pulse (G = 40 G/cm, δ = 25 ms, Δ = 33.2 ms, applied simultaneously along all three Cartesian axes).
