Double quantum spectroscopy using phase rotation at 7T

Abstract

Phase-rotation is an alternative method to phase-cycling in acquisition of magnetic resonance spectroscopic data. Hennig was the first to propose a new method to acquire localised spectroscopic data, where by various scans are stored as rows in a two-dimensional (2D) matrix, which is then doubly Fourier transformed (FT) and a specific row is extracted to represent the 1D spectrum. Phase-rotation was also implemented in a STEAM pulse sequence . The aim of the present work is to implement the phase-roation technique on a high Bo whole body magnet
