ABSTRACT:
Polarization transfer pulse sequences in NMR, such as a DEPT pulse sequence, in combination with a volume selection (for example, VSE) in a body have been described. Therein first volume selection is performed in the body by means of VSE, after which the body is exposed to the DEPT pulse sequence. According to the present invention it is proposed to make the volume selection coincide with the polarization transfer pulse sequence, so that inter alia the pulse sequence is less susceptible to imperfections of rf electromagnetic pulses.
