It should be performed only for a valid medical reason. While MRS can be useful in the diagnosis and Basic Principles and Clinical Applications of Magnetic Resonance Spectroscopy in Neuroradiology Stephan Ulmer, MD,*† Martin Backens, PhD,‡ and Frank J. Ahlhelm, MD‡ Abstract: Magnetic resonance spectroscopy is a powerful tool to assist daily clinical diagnostics. This review is intended to give an overview on Magnetic resonance spectroscopy (MRS) is unproven and not medically necessary. There is a lack of evidence demonstrating that the use of MRS improves health outcomes such as increasing diagnosis rates, reducing the number of unnecessary biopsies, and improving care or treatment planning accuracy in patients Magnetic resonance spectroscopy (MRS) is a noninvasive technique that is used to measure the concentrations of different metabolites within body tissue. The basic scientific principle of MRS is identical to that of magnetic resonance imaging (MRI), except that, instead of anatomical images, PDF | Magnetic resonance spectroscopy (MRS) provides a non-invasive 'window' on biochemical processes within the body.

Sutherland Abstract: Of primary central nervous system tumors treated each year, the majority are glioma, followed by meningioma and then pituitary adenoma.

Magnetic Resonance image guided radiotherapy (MRgRT) offers an opportunity to perform imaging with MR during radiotherapy. MR provides 

Almost all of the reviewed studies involved small, often heterogeneous study populations. The imaging technique varied among the studies.

While magnetic resonance imaging (MRI) identifies the anatomical location of a tumor, MR spectroscopy compares the chemical composition of normal brain 

While MRS can be useful in the diagnosis and At present, MR spectroscopy may be obtained with many clinical 1.5-T MR units and commer- cially available software. Adequate MR spectra may be obtained in periods of time as short as 10 to 15 PDF | Magnetic resonance spectroscopy (MRS) provides a non-invasive 'window' on biochemical processes within the body.
