Spatial localization in NMR spectroscopy in vivo.
Spatial localization techniques are necessary for in vivo NMR spectroscopy involving heterogeneous organisms. Localization by surface coil NMR detection alone is generally inadequate for deep-lying organs due to contaminating signals from intervening surface tissues. However, localization to preselected planar volumes can be accomplished using a single selective excitation pulse in the presence...
متن کامل31-P NMR in the study of liver metabolism in vivo.
Continuous noninvasive readout of biochemical events in body tissues is the goal of many techniques and optical and nuclear magnetic resonance (NMR) approaches seem to be at the forefront of these. Here we present a review of NMR methods for studying liver metabolism in vivo with special emphasis on methods of localizing the response appropriate to the liver itself and to the exclusion of surro...
متن کاملOn Intact Tissues
In recent years the applications of NMR spectroscopy to the analysis of living systems have grown at a rapid pace. Initially these measurements were limited to excised tissues, and later extended to studies of perfused organs. With the new improvements in magnet technology and FT NMR techniques, in vivo measurements of intact animals and humans became possible. Most of these studies concentrate...
متن کاملBioenergetics of Speeding Fish: In Vivo MRS Studies in a 4.7 T Magnetic Resonance
Energetic studies on exercising animals are usually limited to oxygen consumption measurements in respirometers followed by invasive tissue sampling and analysis of metabolites. Noninvasive studies of exercising animals like through the use of P NMR are typically restricted to ‘‘stop and go’’ measurements. Furthermore, magnetic resonance AQ6 studies of marine animals are hampered by sea water, ...
متن کاملSurface coil localization of 31P NMR signals from orthotopic human kidney and liver.
By incorporating the hyperbolic secant inversion pulses with the image-selected in vivo spectroscopy localization technique and by applying a gradient-echo imaging method, we have selected only the 31P NMR signals from orthotopic human kidney and liver, using a single concentric 1H/31P surface coil. Corresponding to the experimental results on animal studies, the phosphocreatine signal is drama...
