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.
