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...
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...
متن کاملClinical applications of proton MR spectroscopy.
Magnetic resonance (MR) spectroscopy has received little attention from the clinical radiology community. Indeed, most MR spectroscopic studies are performed by a small and dedicated group of individuals, mostly basic scientists. This behavior is partly because MR spectroscopy does not produce “pictures” but results in “graphs,” and until lately, it could only be obtained with dedicated units a...
متن کاملProton MR spectroscopy of pediatric cerebellar tumors.
PURPOSE To investigate the role of proton MR spectroscopy in pediatric cerebellar tumor diagnosis. METHODS Single voxel pulse sequences with long echo time (135 or 270 milliseconds, voxel size 8 to 19 cm3), were used to obtain proton spectra of primary pediatric cerebellar tumors. Eleven primitive neuroectodermal tumors (patient age, 2 to 12 years; mean, 7 years), 11 low-grade astrocytomas (a...
