Premature diagnosis
Date: Sep 1, 2006
Author: David Bradley
An MRI scan can help in predicting future developmental outcomes of pre-term infants, according to US researchers. The scan reveals abnormalities no picked up by cranial ultrasound and can be used to predict problems that would become apparent by age two years.

Impact of evidence-based medicine on magnetic resonance spectroscopy
Date: Aug 23, 2006
Author:
Magnetic resonance spectroscopy is a robust, non-invasive means of defining aspects of human neurochemistry. After more than two decades, it is clear that in addition to its scientific interest, MRS has diagnostic value in many areas of evidence-based medcine. Read the full paper taken from the recent special issue of NMR in Biomedicine dedicated to clinical MRS.

A mind for politics
Date: Aug 1, 2006
Author: David Bradley
Beware MRI machines if you're a political mole in the candidate's office spying for the other side. Researchers in the US have demonstrated that functional MRI can reveal the differences in brain activity when a political partisan looks at the faces of politicians of different political persuasion. Apparently, cognitive networks in the brain that regulate emotion kick into action when a true blue supporter sees the face of an opposition candidate.

Gd-enhanced MR images of substrates other than water
Date: Jul 25, 2006
Author:
This communication from the new journal, Contrast Media & Molecular Imaging, reports the dramatic relaxation enhancements that can be obtained upon the interaction of substrates like lactate, trifluorolactate and inorganic phosphate with the paramagnetic GdDO3A agent.

Playing tag to detect heart problems
Date: Jul 1, 2006
Author: David Bradley
Tagged MRI is challenging conventional views regarding atherosclerosis and latent heart problems in patients that otherwise appear healthy and present no symptoms. By tagging different tissue prior to a scan, researchers can obtain a detailed view of the movement and function of those tissues. Now, US researchers have investigated whether tagged MRI can reveal risk factors for cardiovascular disease before obvious symptoms occur.

Prospective longitudinal proton magnetic resonance spectroscopic imaging in adult traumatic brain injury
Date: Jun 26, 2006
Author:
The purpose of this study was to investigate whether longitudinal magnetic resonance proton spectroscopic imaging demonstrates regional metabolite abnormalities after traumatic brain injury that predict long-term neurologic outcome.

Nano cancer scanner
Date: Jun 1, 2006
Author: David Bradley
X-ray imaging is a very mature, although not infallible, field of medicine, but it does not lend itself to the detection of small tumours or their metastases. Now, Sangeeta Bhatia in Boston, Massachusetts and colleagues at the Harvard-MIT Division of Health Sciences and Technology hope to remedy that by using iron oxide nanoparticles to allow MRI to visualize areas of tumor invasion.

Accelerated parallel imaging for functional imaging of the human brain
Date: May 19, 2006
Author:
Read this recent paper taken from the Special Issue of NMR in Biomedicine dedicated to parallel imaging techniques. Accelerated parallel imaging techniques have recently been applied to functional imaging experiments of the brain to improve the performance of commonly used single-shot techniques such as echo-planar imaging.

Iron on the brain
Date: May 1, 2006
Author: David Bradley
The largest-ever study of iron accumulation in the brain has been undertaken using MRI. The study demonstrates how this technique can reveal concentration differences between regions of the brain in living patients. For the first time, gender differences in iron concentrations have been observed, according to the researchers. The results could lead to new understanding of how iron accumulation in the brain is associated with the risk of degenerative brain diseases such as Alzheimer's, Parkinson's and...

Proton MRS of early post-natal mouse brain modifications in vivo
Date: Apr 18, 2006
Author:
The aim of thi study was to apply reliable in vivo MRS techniques for non-invasive investigations of brain development in normal and transgenic mice, by monitoring metabolite concentrations in different brain regions.
