Proton MR Spectroscopy
Nuclear magnetic resonance spectroscopy (MRS) has been in use in biochemistry labs for more than 50 yr. In its earlier years, it was used primarily for in vitro chemical analysis of small samples. Magnetic resonance imaging (MRI) is a powerful imaging technique that combines exquisite sensitivity to soft tissue contrast with the ability to demonstrate anatomy in many different planes and projec...

Maly Radiology, University of Michigan, Ann Arbor, MI, United States, School of Public Health, University of Michigan, Ann Arbor, MI, United States, Radiology, University of Lund, Malmoe, Scania, Sweden Purpose:To explore the ability of 2D-CSI MR spectroscopy in differentiating radiation injury versus tumor recurrence in patients previously...
متن کاملExtraneous lipid contamination in single-volume proton MR spectroscopy: phantom and human studies.
PURPOSE To determine the degree of extraneous lipid contamination in defined volumes of interest studied with single-volume proton MR spectroscopy. METHODS Single-volume proton MR spectroscopy was performed on a fat/water phantom and in three volunteers using the stimulated-echo acquisition mode (STEAM) and point-resolved spectroscopy (PRESS) localization methods. Three different volumes of i...
متن کاملProton MR spectroscopy of Sjögren-Larsson's syndrome.
We performed single-voxel proton MR spectroscopy (1H-MRS) in two children with Sjögren-Larsson's syndrome (SLS). Both patients showed two abnormal spectral peaks at 1.3 ppm and 0.9 ppm that were obtained with short echo times. These two abnormal spectral peaks were seen in high-intensity areas on T2-weighted images and also in basal ganglia of normal intensities. 1H-MRS may be useful for establ...
متن کاملProton MR spectroscopy of tumefactive demyelinating lesions.
BACKGROUND AND PURPOSE Tumefactive demyelinating lesions (TDLs) can simulate intracranial neoplasms in clinical presentation and MR imaging appearance, and surgical biopsy is often performed in suspected tumors. Proton MR spectroscopy has been applied in assessing various intracranial diseases and is increasingly used in diagnosis and clinical management. Our purpose was to determine if multivo...
