Fig 6. Unfolding artifacts from the globes in ASSET-accelerated DWI. A, The b = 0 s/mm² image acquired at 3T with an ASSET acceleration factor of R = 2 shows unfolding artifacts from the distorted high-signal-intensity globes appearing as dark bands in the occipital regions (black arrows) as well as a bright band in the anterior left temporal lobe (black arrowhead). B, The unfolding artifacts are not apparent on the combined DWI image because the globes contain fluid with high diffusivity; therefore, the globes signal intensity is suppressed by the diffusion gradients. C, However, the unfolding artifacts are again apparent on the ADC map (white arrows and arrowhead) because the b = 0 s/mm² image is required for ADC calculation (equation 5, Part I¹).
