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.
