Figure 7

Four different images obtained using the sequence shown in Figure 6a for (a) and (c), and using the sequences of Figure 6b for (b) and (d). All images were obtained with a total matrix size of 64 × 64 with four-fold interleaving, an FOV of 27.0 × 27.0 mm, and TE = 14.4 ms. The lengths of the excitation pulses were 384 µs in all cases. In (a) and (b) the amplitude of the constant time-encoding gradient was 13.6 Gcm⁻¹ = 0.136 Tm⁻¹ causing significant signal losses due to diffusion, while in (c) and (d) the amplitude of this gradient was attenuated to 6.8 Gcm⁻¹ = 0.068 Tm⁻¹ to decrease signal losses.
