A Zero Echo Time (ZTE) sequence compatible with
conventional phased array coils was implemented and
optimized at 7T for brain imaging with more uniform T1
contrast and high sensitivity while retaining
sensitivity to fast relaxing spins. Details of the
implementation and optimization are provided along with
images from phantoms and normal volunteers. Comparison
is provided to a conventional 3D inversion prepared
gradient echo imaging sequence of equal scan time. An
additional feature of the sequence is that it generates
very low levels of acoustic noise.
