Voting and image

Date: Nov 1, 2008

Author: David Bradley

Functional magnetic resonance imaging studies reveal that voters are persuaded more by the negative aspects of a politician's looks than by the positive features. The findings apply specifically if the voter was previously unaware of the politician. Ahead of the US elections, voters there should read on but let their political conscience guide their voting decision.

Prognostic MRI biomarkers of treatment efficacy for retinopathy

Date: Oct 22, 2008

Author:

There is a pressing need for retina-specific imaging biomarkers that robustly measure early changes in physiology, are linked to the histopathology responsible for vision loss, and, importantly, predict treatment efficacy. In this paper, the authors conclude that functional MRI biomarkers are most promising for prognostic evaluation of treatment efficacy earlier in the course of retinopathy than is currently possible.

Anticipating excitation

Date: Oct 1, 2008

Author: David Bradley

Functional magnetic resonance imaging (fMRI) has revealed a reason why the excitement of unwrapping presents dwindles as our brains get older and more jaded. According to a new study, a biochemical pathway is responsible for mellowing our expectations.

Identification and characterisation of childhood cerebellar tumours by in vivo proton MRS

Date: Sep 22, 2008

Author:

1H MRS has great potential for the clinical investigation of childhood brain tumours, but the low incidence in, and difficulties of performing trials on, children have hampered progress in this area.

Bending MRI to diagnose joint disease

Date: Sep 1, 2008

Author: David Bradley

Magnetic resonance imaging could provide an early diagnosis of osteoarthritis (OA), the most common form of arthritis, according to scientists speaking at the recent meeting of the American Chemical Society.

An investigation of human brain tumour lipids by high-resolution magic angle spinning 1H MRS and histological analysis

Date: Aug 21, 2008

Author:

NMR-visible mobile lipids are important biomarkers in the diagnosis of brain tumours and monitoring the effects of treatment response.

Magnetic insights

Date: Aug 1, 2008

Author: David Bradley

A new MRI technique has been developed to allow physicists to see deep within tiny magnets. The technique could improve our understanding of magnetism at the fundamental level and lead to better computer hard drives and perhaps even new small-scale MRI instruments.

Here comes colour

Date: Jul 1, 2008

Author: David Bradley

Not everything is black and white, perhaps with the exception of MRI. Aside from the artificial colours that can be added by computer, MRI is a technique of contrasts and greyscales. However, that could all change soon thanks to the ongoing development of microscopic magnetic particles by researchers in the US who hope to bring a little colour to MRI.

Non-invasive detection of hippocampal sclerosis: correlation between metabolite alterations detected by 1H-MRS and neuropathology

Date: Jun 23, 2008

Author:

In this paper, the authors assessed 1H-MRS as a screening tool for detection of hippocampal sclerosis in patients with temporal lobe epilepsy.

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.
