Fast, Volumetric and Silent Multi-contrast Zero Echo Time Imaging
Proceedings of the International Society of Magnetic Resonance in Medicine (ISMRM), Hawaii, USA, April 2017 (bib)

The current work aims to provide a volumetric, fast and silent method for quantitative T1 mapping with Zero Echo Time (ZTE) imaging, and generate multiple T1-weighted images at virtual inversion times. By designing an interleaved radial trajectory for ZTE, and constraining the temporal behavior of the signal with low-dimensional subspace and spatiotemporal low rank regularization, we conducted a volumetric T1 mapping in 2 minutes with acoustic noise only 1.1dB higher than scanner background.
