Abstract:
1. A method of performing multiplex RARE magnetic resonance imaging having slice selective excitation of two or more slices and of one or more nuclei followed by a refocusing of these slices and an application of gradient pulses, which cause a division of the signal into spin echoes and stimulated echoes, the method comprising the steps of: a) performing slice selective excitation of two or more slices and of one or more nuclei; b) applying, following step a), refocusing slice selective RF pulses, which are placed in order to fulfill an echo-spacing CPMG condition for each slice; c) arranging the gradient pulses, which cause a phase accumulated by spins in each slice between two consecutive refocusing RF pulses corresponding to that slice to be equal, thus fulfilling a CPMG phase accumulation condition; and d) measuring and analyzing NMR signals emanating from the one or more nuclei in order to complete the multiplex RARE magnetic resonance imaging method.
