A family of fast chemical-shift imaging techniques, which takes advantage of the cylindrical symmetry found, for instance, in some plants, is introduced. Variants with one and two spectral dimensions allow rapid measurement of the radially dependant spatial distribution of metabolites in such objects. Compared to conventional chemical-shift imaging and correlation-peak imaging, the minimal experimental duration can be reduced substantially. The impact on the SNR is discussed. Radial spectroscopic 1 H NMR images of metabolites in Ancistrocladus heyneanus, a tropical liana plant, are shown, using both radial chemical-shift imaging and radial correlation-peak imaging. The spatial distribution of various metabolites in this plant have been measured. The reduction of experimental duration compared to the conventional techniques was by a factor of 63 and 31, respectively.
