ABSTRACT:
A method of reproducing the lactate distribution in a slice comprises first and second sequences, each comprising generating at least three rf pulses. The first sequence is such that the resultant stimulated echo signal remains uninfluenced by the lactate components, the second sequence is such that the stimulated echo signal is determined by the lactate component. A group of difference signals is formed by subtracting the two stimulated echo signals and repeating of these sequences with encoding gradients which vary as regards strength and/or direction, the group is suitable for determining the desired distribution by two-dimensional Fourier transformation.
