متن کاملTwo-dimensional proton echo-planar spectroscopic imaging of brain metabolic changes during lactate-induced panic.
BACKGROUND A fast, proton echo-planar spectroscopic imaging (PEPSI) technique, capable of simultaneously measuring metabolites from multiple brain regions, was used to investigate the anatomical distribution and magnitude of brain lactate responses to intravenous lactate infusion among subjects with panic disorder and control subjects. METHODS Fifteen subjects with panic disorder and 10 contr...
متن کاملSpectroscopic imaging using concentrically circular echo-planar trajectories in vivo.
An alternative to the standard echo-planar spectroscopic imaging technique is presented, spectroscopic imaging using concentrically circular echo-planar trajectories (SI-CONCEPT). In contrast to the conventional chemical shift imaging data, the sampled data from each set of concentric rings were regridded into Cartesian space. Usage of concentric k-space trajectories has the advantage of requir...
متن کاملProton-Echo-Planar-Spectroscopic-Imaging (PEPSI) in Human Breast
INTRODUCTION MR single voxel spectroscopy (MRS) to measure Choline in breast tumors has shown promise as a diagnostic adjunct to dynamic contrast-enhanced MRI exam. MRS improved the sensitivity, specificity, and accuracy for all readers, and improved the inter observer agreement between the readers [1,6]. However, single voxel spectroscopic techniques do not allow characterization of lesion het...
متن کاملHigh-Resolution Echo-Planar Spectroscopic Imaging of the Human Calf
BACKGROUND This study exploits the speed benefits of echo-planar spectroscopic imaging (EPSI) to acquire lipid spectra of skeletal muscle. The main purpose was to develop a high-resolution EPSI technique for clinical MR scanner, to visualise the bulk magnetic susceptibility (BMS) shifts of extra-myocellular lipid (EMCL) spectral lines, and to investigate the feasibility of this method for the a...
