Improved efficiency in 2DFT magnetization-prepared rapid gradient echo imaging: application to abdominal imaging.
The incorporation of the phase offset multi planar (POMP) technique into breathheld magnetization-prepared gradient echo imaging is discussed as a means for improving imaging efficiency without sacrificing resolution, contrast, or SNR improvement. The phase encoding order necessary to preserve the centric approach is described. When combined with interleaving, the POMP technique enables four 256 x 256 images to be acquired in a 12-s breathhold, doubling the efficiency of the original technique. This scan efficiency is compared with that of other T1-weighted 2DFT methods.
