摘要： MRI device arranged to a) generate a series of MR echo signals from a nuclear spin series having two or more spectral lines by subjecting at least part of a body (7) to an MR imaging pulse sequence using multiple time-encoding echo time values, b) acquire the MR echo signals for reconstructing a series of time-encoded MR images therefrom, each time-encoded MR image being associated with one of the time-encoding echo time values, c) transform the series of time-encoded MR images into a series of spectral domain MR images on a pixel-by-pixel or voxel-by- voxel basis, d) and superimpose the MR images for obtaining a final image the device being further arranged to apply a time-encoding scheme in step a) such that each spectral line of the nucle'ar spin species is uniquely mapped to one MR image from the series of spectral domain MR images.
