A novel 3D multi-contrast imaging technique using
the hybrid acquisition of FSE and GRE provided T1 weighted, T2 weighted and
FLAIR images simultaneously.
The comparison with conventional 3D imagings in term
of image contrast and scan time demonstrated a promising result.

SCETA (Serial Connection of Echo Train acquisition) to acquire T1w, T2w and
FLAIR using the hybrid acquisition of FSE and GRE. (b) Echo signal of white
matter, gray matter and CSF builds three imaging contrasts in a TR.

comparsion result with conventional 3D scan of T2w, FLAIR and T1w. SCETA
reduces scan time by a factor of approximately 2.4 while maintaining similar
image appearance to conventional scan.
