Zero echo time (ZTE) imaging enables efficient direct MRI of tissues with very rapid transverse relaxation. In addition, this intrinsically three-dimensional technique is also very fast, has high robustness against eddy current and off-resonance effects, and the acoustic noise of the sequence is close to ambient level. All these beneficial properties make ZTE imaging also attractive beyond short-T2 applications. However, due to zero TE and usually small flip angles, intrinsic contrast mechanisms are somewhat limited. Therefore, in the present work, magnetisation preparation is used to create T1 contrast in ZTE images.
