In this study we implemented a new dual-echo sequence
for simultaneous acquisition of T1 and T2* weighted 3D
Anatomical images. An echo-specific K-space reordering
scheme was used to separately satisfy T1 and T2*
contrast for the two echoes, which was determined to be
30 and 10-20 for the first echo and second echo,
respectively. The results showed that the proposed
method enables us to acquire both 3D T1 and T2* weighted
images with scan time of ~3 min and a reasonable spatial
coverage and resolution. The technique may be helpful
for accelerating routine clinical studies requiring T1
and T2* acquisitions.
