Clinical 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 کاملMR Spectroscopy: Clinical Applications
On clinical MR systems the proton is the most widely used nucleus for applications of magnetic resonance spectroscopy (MRS). The widespread biological applications of 1 H-MRS cannot be covered in detail, but exemplary uses will be discussed or referred to. Clinical applications fall into two categories: clinical research vs. clinical routine, where the former primarily aims at average responses...
متن کاملIn vivo proton MR spectroscopy of the breast.
In vivo proton magnetic resonance (MR) spectroscopy (hydrogen 1 spectroscopy) provides useful information about the pathology of breast lesions by the measurement of diagnostic chemicals visible on the MR timescale. Spectroscopic measurements may be obtained following contrast-enhanced MR imaging by applying a point-resolved spatially localized spectroscopy sequence. The observation of resonanc...
متن کاملClinical applications of MR spectroscopy in oncology
Introduction One of the first applications of Magnetic Resonance Spectroscopy (MRS) to a patient with a tumor was the detection of an abnormal P MR spectrum of a rhabdosarcoma as compared to that of muscle tissue [1]. A typical tumor feature, already evident in this spectrum, was the relatively high level of the so-called phosphomonoester peak, which contains resonance’s from phosphorylated cho...
متن کاملProton MR spectroscopy-detectable major neurotransmitters of the brain: biology and possible clinical applications.
Neurotransmitters are chemical substances that, by definition, allow communication between neurons and permit most neuronal-glial interactions in the CNS. Approximately 80% of all neurons use glutamate, and almost all interneurons use GABA. A third neurotransmitter, NAAG, modulates glutamatergic neurotransmission. Concentration changes in these molecules due to defective synthetic machinery, re...
