Abstract
In a multi-echo magnetic resonance imaging method a number of high-frequency pulses are generated involving a high-frequency excitation pulse and a number of following high-frequency refocusing pulses, at least two phase encoding gradient pulses are respectively generated between the high-frequency refocusing pulses, and at least two compensation phase encoding gradient pulses are generated between the high-frequency excitation pulse and the first high-frequency refocusing pulse.
