Fig. 1.

From left to right: 1-, 2-, 4- and 8-shot spin-echo EPI (SE-EPI), conventional spin-echo (c-SE) and gradient-echo (GE) images, acquired at the level of C1/C2, C3 and C7. In-plane resolution is identical for each sequence (133 × 133 µm²). Scan times for the acquisition of the seven slice series (C1–C7) are, respectively, equal to: 0.42, 0.83, 1.66, 3.33, 10.67 and 4.48 min
