This work describes a method for creating
short-T2-selectivity in excitation without preparatory
pulses and demonstrates its use with UTE imaging. The
method described is also appropriate for controlling
short-T2 contrast in ZTE imaging. Bone structure imaged
using a multi-echo UTE sequence with multiple
T2-selective excitation pulses to highlight short-T2
components. The structures represented in MRI are
verified by comparison to CT images of the same
subjects.
