摘要： The invention relates to a device for magnetic resonance imaging of a body (7) placed in an examination volume, the device (1) comprising means (2) for establishing a substantially homogeneous main magnetic field in the examination volume, means (3, 4, 5) for generating switched magnetic field gradients superimposed upon the main magnetic field, means (6) for radiating RF pulses towards the body (7), control means (12) for controlling the generation of the magnetic field gradients and the RF pulses, means (10) for receiving and sampling magnetic resonance signals, and reconstruction means (14) for forming MR images from the signal samples. According to the invention, the device (1) is arranged to a) generate a series of MR echo signals from a nuclear spin species having two or more spectral lines by subjecting at least a portion of the 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) superimpose the MR images for obtaining a final image.
