Magnetic Resonance Spectroscopy
Journal of Neuro-Ophthalmology, 2005Magnetic resonance spectroscopy (MRS) complements magnetic resonance imaging (MRI) as a non-invasive means for the characterization of tissue. While MRI uses the signal from hydrogen protons to form anatomic images, proton MRS uses this information to determine the concentration of brain metabolites such as N-acetyl aspartate (NAA), choline (Cho ...

MAGNETIC RESONANCE SPECTROSCOPY
Neuroimaging Clinics of North America, 1995Magnetic resonance spectroscopy, like PET, allows cerebral function to be assessed neuro-anatomically. In addition to being noninvasive and not requiring ionizing radiation, this technique can be performed with equipment available at most medical centers.

Magnetism and magnetic resonance
2006Abstract in which are developed the fundamental physics of the single isolated magnetic dipole, materials as ensembles of such dipoles, their resonant behaviour, and magnetic field measurements. This provides the under lying physics for chapter 7.

MAGNETIC RESONANCE CHOLANGIOGRAPHY
Gastroenterology Clinics of North America, 1995MR cholangiography offers a noninvasive method of obtaining images of the biliary system without the use of a contrast agent. There is no radiation exposure. Pulse sequences can be chosen to obtain bright bile or black bile cholangiograms. Image processing algorithms can be selected to obtain a three-dimensional representation of biliary anatomy and ...

[Cerebrovascular pathology. Comparison of magnetic resonance and magnetic resonance angiography].
La Radiologia medica, 1991After making the visualization of the intracranial circulation possible without contrast media, the radiologist is now evaluating the diagnostic role of the different techniques of MRA. Attempts are also being made to characterize the main patterns of intracranial vascular diseases.

Abdominal Imaging, 2008
Excellent contrast resolution and lack of ionizing radiation make magnetic resonance urography (MRU) a promising technique for noninvasively evaluating the entire urinary tract. While MRU currently lags behind CT urography (CTU) in spatial resolution and efficiency, new hardware and sequence developments have contributed to a resurgence of interest in ...

Magnetic Resonance Cholangiopancreatography
Seminars in Roentgenology, 2008Magnetic resonance cholangiopancreatography (MRCP) is a noninvasive imaging technique for the evaluation of pancreatico-biliary disorders. It uses magnetic resonance imaging to visualize fluid in the biliary and pancreatic ducts as high signal intensity on T2-weighted sequences and provides improved spatial resolution and permits imaging of the entire ...

Magnetic resonance mammography
BMJ, 2010Routine use in newly diagnosed breast cancer patients is unsupported Magnetic resonance imaging enables high definition scanning of tissue without the use of ionising radiation. In the past decade it has become widely used in breast imaging and is a sensitive method of visualising the breast parenchyma and highlighting areas of pathology.

The principles of magnetic resonance
British Medical Bulletin, 1989Magnetic Resonance (MR), which has no known biological hazard, is capable of producing high resolution thin tomographic images in any plane and blocks of 3-dimensional information. It can be used to study blood flow and to gain information about the composition of important materials seen and quantified on dimensionally accurate images. The MR image is
