MRI scans and mastectomy
Date: Jun 1, 2008
Author: David Bradley
MRI breast scans are associated with more mastectomies. That is the conclusion from a study by Mayo Clinic researchers in the USA. They have found that after an earlier, seven-year decline, there has been a sharp rise in the number of whole-breast mastectomies.

Rewiring brains therapeutically
Date: May 1, 2008
Author: David Bradley
US researchers have used MRI studies to demonstrate that a form of rehabilitation therapy for treating the effects of stroke causes the brain to repair itself.

Fast nosological imaging using canonical correlation analysis of brain data obtained by two-dimensional turbo spectroscopic imaging
Date: Apr 28, 2008
Author:
A new fast and accurate tissue typing technique has recently been successfully applied to prostate MR spectroscopic imaging data. This technique is based on canonical correlation analysis, a statistical method able to simultaneously exploit the spectral and spatial information characterizing the MRSI data.

Video nasties
Date: Apr 1, 2008
Author: David Bradley
US researchers have used functional magnetic resonance imaging (fMRI) for the first time to monitor how the brain copes with disgust while watching video nasties. They found that the grin and bear it approach does not work nearly so well as positive reappraisal of the images one is seeing.

Gender-related and age-related urinalysis of healthy subjects by NMR-based metabonomics
Date: Mar 26, 2008
Author:
NMR-based metabonomic analysis is a well-established approach to characterizing healthy and diseased states. The aim of this study was to investigate inter-individual variability in the metabolic urinary profile of a healthy population, not subjected to strict dietary limitations, by NMR-based metabonomics.

Men play, women left unrewarded
Date: Mar 1, 2008
Author: David Bradley
The latest results from functional MRI suggest a possible explanation as to why males enjoy, and even become addicted to, video games more commonly than females. Allan Reiss and colleagues at Stanford University School of Medicine have shown that one of the brain's reward centres is simply more active during video-game play in men than in women.

Fast screening of paramagnetic molecules in zebrafish embryos by MRI
Date: Feb 25, 2008
Author:
Zebrafish embryo is a well-established model used in many fields of modern experimental biology. In this paper the authors demonstrate that it provides a promising model platform for exploring fundamental MR aspects that can be used to screen and study active MR molecules before progressing to more complex living systems.

Cultural exchange
Date: Feb 1, 2008
Author: David Bradley
According to the latest results from functional magnetic resonance imaging (fMRI) studies, people from East Asian cultures use their brains differently from people immersed in American culture when solving the same visual mental tasks. The findings could have implications for understanding how culture affects behaviour.

In vivo proton magnetic resonance spectroscopy in patients with mood disorders: A technically oriented review
Date: Jan 30, 2008
Author:
Proton MR spectroscopy (1HMRS) has been extensively used among mood disorders patients. A review of some of the published literature in 1HMRS studies of mood disorders is published here in this recent paper taken from the Journal of Magnetic Resonance Imaging.
