Three-Dimensional gradient echo sequence named THRIVE and e-THRIVE needs better contrast and lower artifact for pelvis image with Contrast enhacement. Adopted centric-radial k-space tarajectory as THRIVE result in good contrast,but blurring is outstanding. And adopted linear k-space trajectory combined partial Fourier transformation as e-THRIVE improved blurring of THRIVE, but truncation influences image using e-THIRVE.Furthermore,adopted linear radial k-space trajectory as Liner-THRIVE was able to improve disadvantage of THRIVE and e-THRIVE.
