Three-dimensional phase-encoded chemical shift MRI in the presence of inhomogeneous fields

By Vasiliki Demas, Dimitris Sakellariou, Carlos A. Meriles, Songi Han, Jeffrey Reimer and Alexander Pines


A pulse sequence consisting of an excitation pulse and two adiabatic full-passage pulses with scaled relative peak amplitudes is combined with phase encoding to recover chemical shift information within 3D images in a 1D inhomogeneous static magnetic field with a matched rf field gradient. The results are discussed in the context of ex situ magnetic resonance and imaging. The future directions of our research in implementing the ex situ technique in a real one-sided system are also discussed
