FIGURE 2.
Representative slices from the reconstructed images for a subject with cystic fibrosis before registration and bias correction. White arrows point to a defect; blue arrows point to a hyperintense region of airway; and red arrows point to a hyperintense region likely caused by a defect shunting xenon into other regions of the lung. Each row corresponds to 1 of 4 sequences/settings used: top, 2D GRE (comparative); upper middle, 3D radial (comparative); lower middle, FLORET (comparative); and bottom, FLORET (fully sampled). Note that the 2D-GRE slices are approximately 3 times thicker than the corresponding in-plane resolution and the resolution in all planes for the comparative FLORET. All other images are fully isotropic
