Zero Echo Time (ZTE) imaging enables ultra-fast, near silent data acquisition. In this work we demonstrate how contrast-to-noise, between white and gray matter in the brain, with a ZTE acquisition changes with field strength. At low field strength, maximum contrast is achievable with low RF power, which is promising for implementation on low field systems. We demonstrate through in vivo experiment that ZTE imaging can be performed at 1.5T/3T/7T, and how variable flip angle data at, for instance, 1.5T can be used for synthesising high quality T1-weighted MR images.
