Simultaneous T1 and T2* weighted 3D Anatomical Imaging using a Dual-Echo Sequence

Abstract

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.
