ABSTRACT:
Nuclear spins are excited in an examination subject by a sequence of radio-frequency pulses that are emitted in under the influence of slice selection gradients, with n different slices of the examination subject being excited. Due to read-out gradients, n gradient echoes respectively allocated to a slice are generated such that each gradient echo allocated to a radio-frequency pulse comes to lie between two successive radio-frequency pulses. Further slices can thus be excited within the echo time of a gradient echo of a specific slice. A T.sub.2.sup.* contrast image can thus be obtained with a significantly shorter examination time than was heretofore achievable.
