title: Metabolite monitoring in plants with double-quantum filtered chemical shift imaging.
abstract: 1H spectroscopic imaging in combination with double-quantum filtering with magnetic field gradients is used for in vivo applications in humans and animals. Because of its high selectivity and strong reduction of water signal it is also a useful tool for monitoring the distribution of specific metabolites in plants. The development and application of a double-quantum selective spectroscopic imaging sequence for detecting the sucrose distribution in the stem of sugar cane (Saccharum officinarum L.) is described. The results show that local differences in sucrose distribution can be detected non-invasively with a resolution of 0.4x0.4x6 mm(3) to 0.645x0.645x6 mm(3).
