Effective
imaging of short T2 species requires efficient suppression of longer T2 tisues
to maximize short T2 contrast and dynamic range. While inversion with segmented
k-space acquisition in Cartesian schemes is straightforward, inversion with segmented
k-space UTE radial acquisition offers some challenges since the center of
k-space is sampled with each acquisition resulting in magnetization modulation
related artifacts. Here we perform 3D inversion recovery dual-echo UTE imaging
of lung parenchyma using a reordered k-space radial scheme to perform artifact
free high contrast imaging of native lung parenchyma.
