Measurement sequences for single voxel proton MR spectroscopy.
Proton spectroscopy is easy to perform at clinically used whole body MR scanners, since the necessary hardware is identical to that of MR imaging. Only specific measurements sequences for the acquisition of volume selected spectral information and appropriate evaluation software have to be installed. Several techniques for a volume-selective spectroscopy have been proposed, but only two are wid...
متن کاملUsefulness of Single Voxel Proton MR Spectroscopy in the Evaluation of Hippocampal Sclerosis
OBJECTIVE The purpose of our study was to determine the ability of H-1 MR spectroscopy (MRS) to lateralize the lesion in patients with hippocampal sclerosis. MATERIALS AND METHODS Twenty healthy volunteers and 25 patients with intractable temporal lobe epilepsy whose MR imaging diagnosis was unilateral hippocampal sclerosis were included. This diagnosis was based on the presence of unilateral...
متن کاملEffect of voxel position on single-voxel MR spectroscopy findings.
BACKGROUND AND PURPOSE Single-voxel MR spectroscopy is a widely used tool for evaluating brain tumors. Although extensive data are available on the MR spectral appearance of tumors, less is known about the effect of voxel position on the accuracy of single-voxel MR spectroscopy findings. The purpose of this study was to test the hypothesis that the accuracy of single-voxel MR spectroscopy in th...
متن کاملProton MR spectroscopy in patients with complex partial seizures: single-voxel spectroscopy versus chemical-shift imaging.
BACKGROUND AND PURPOSE Proton MR spectroscopy has recently been applied to the evaluation of seizures, but few comparisons have been made between different clinical spectroscopic techniques. Our goal was to determine whether there is a significant difference between hippocampal NAA/(Cho+Cr) ratios obtained by single-voxel spectroscopy (SVS) and by chemical-shift imaging (CSI). METHODS Twelve ...
متن کاملSingle-voxel proton MR spectroscopy of nonneoplastic brain lesions suggestive of a neoplasm.
BACKGROUND AND PURPOSE MR spectroscopy is used to characterize biochemical components of normal and abnormal brain tissue. We sought to evaluate common histologic findings in a diverse group of nonneoplastic diseases in patients with in vivo MR spectroscopic profiles suggestive of a CNS neoplasm. METHODS During a 2-year period, 241 patients with suspected neoplastic CNS lesions detected on MR...
