FIG. 8.

This figure shows the out-of-plane sagittal views of (a) the axial and (b) the coronal FSE scans of a TSC patient, (c) the corresponding sagittal view of a T1W MPRAGE scan, and (d) the corresponding sagittal view of a FLAIR scan of the same patient; the arrows show the slice select direction on the FSE scans; circles highlight some of the thin structures with axis that were almost exactly parallel to the slice select direction in the coronal FSE scan so could be appropriately visualized on the coronal FSE scan despite the 2 mm slice thickness. Image (b), on the other hand, shows that these thin structures may easily be obscured by partial volume effect when they are not parallel to the slice select direction. Although the details of the anatomy have been visualized on the high-resolution MPRAGE and FLAIR scans, many of these structures, such as the abnormal radial bands of white matter, are best visualized by T2W FSE scan.
