In vivo single-voxel proton MR spectroscopy in intracranial cystic masses.
PURPOSE Our objective was to evaluate the proton MR spectroscopic pattern of the cystic contents of various intracranial masses and to report characteristic spectral patterns that may be helpful in the differential diagnosis of these lesions. METHODS We evaluated 40 proton MR spectra obtained from cystic contents of various intracranial cystic masses in 39 patients, including gliomas (n = 14)...
متن کاملMeasurement 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 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...
