Rapid FLASH (fast low angle shot) NMR images are very sensitive to flow phenomena. In particular, a steady reflow of unsaturated spins from outside the imaging plane results in high image intensities which depend on the flip angle, the repetition time, and the flow velocity. Here we describe a techn
A method of 31P FLASH NMR imaging is described using a low flip angle excitation pulse and three-dimensional Fourier transform spectroscopic imaging (3DFT). In vivo high-resolution 31P NMR spectra are obtained for each of 32 x 32 image elements using a minimum measuring time of 1.5 min. 31P FLASH im
A fast method for quantitative NMR imaging of flow velocities in intact plants is described. The purpose of this method is to observe dynamic changes of flow velocity in the xylem of plants after fast changes of environmental conditions. The spatial image resolution is 47 Ψ 188 m 2 in-plane. The met
