Efficient T2*- Contrast Manipulations in 3D Abdominal Imaging Using Autocorrected Forward/Reverse Spiral MRI

Large volume coverage, short total scan time, robust fat suppression and dedicated measures to varyimage contrast are important issues in abdominal MRI. To manipulate T2* weighting from very weak to very strong, 3D single breath-hold forward and reverse spiral imaging is performed in combination with three-point chemical-shift imaging (IDEAL) for high quality fat suppression and off-resonance artifact correction. Parallel imaging was employed to improve SNR, sampling efficiency and to achieve an up-front data compression during image reconstruction and correction. The combination of forward/reverse spiral signal sampling, IDEAL and SENSE could pave the way for interesting future water / fat resolved clinical applications.
