    fig 1.

    Images of a 35-year-old male volunteer.

    A, Axial 4-GRASE b0 image, 4615/119/4 (TR/TEeff/excitations), obtained at the level of the temporal lobe base.

    B, Single-shot spin-echo echo-planar b0 image, 5538/96/4, obtained at the level of the temporal lobe base.

    C, Thresholded binary image generated from single-shot spin-echo echo-planar b0 image.

    D, Difference image obtained by subtracting the binary maps of the 4-GRASE b0 images from the binary map of the T1-weighted spin-echo image.

    E, Difference image obtained by subtracting the binary maps of the single-shot spin-echo echo-planar b0 images from the binary map of the T1-weighted spin-echo image. Note that the distortion index (number of pixels in the black zone) is greater for the subtracted image E than D, which is the result of more severe distortion in the single-shot spin-echo echo-planar b0 images, as shown by thick bands of signal loss (*) and signal hyperintensity (arrows).

    fig2.Images of a 34-year-old male volunteer.

    A, Axial single-shot spin-echo echo-planar 3429/96/4 MR image, obtained at the level of the basal ganglia. The single-shot spin-echo echo-planar diffusion-weighted MR image and the corresponding maps (B, C) show a greater degree of distortion of the frontal lobes around the frontal sinuses and a higher SNR than do the 4-GRASE diffusion-weighted MR image and maps (D, E, F).

    B, Corresponding ADCi map.

    C, Corresponding FA map.

    D, 4-GRASE 4286/119/4 diffusion-weighted image, obtained at the level of the basal ganglia.

    E, Corresponding ADCi map.

    F, Corresponding FA map.

    fig 3.

    Images of a 34-year-old male volunteer (same volunteer as in fig 2).

    A, Axial 4-GRASE 4286/119/4 image, obtained at the level of the lateral ventricle body.

    B, Corresponding ADCi map.

    C, Corresponding FA map.

    D, 10-GRASE 4286/119/10 diffusion-weighted MR image, obtained at the level of the lateral ventricle body. As expected, the 10-GRASE diffusion-weighted MR image and maps (D, E, F) show higher SNR than the 4-GRASE diffusion-weighted MR image and maps (A, B, C) at the expense of longer acquisition time.

    E, Corresponding ADCi map.

    F, Corresponding FA map.
