ABSTRACT:
A nuclear magnetic resonance apparatus for the examination of a subject has coils for respectively generating fundamental and gradient magnetic fields in which the examination subject is disposed, and a radio-frequency measurement unit which irradiates the examination subject with a sequence of radio-frequency pulses and which acquires the nuclear magnetic resonance signals emitted from the examination subject. The pulse sequences generated by the radio-frequency measurement unit are selected such that information for two differently emphasized spin-echo images and information for a T.sub.1 -emphasized image from a stimulated echo are acquired in one sequence.
