Rapid eye scan in multiple sclerosis
Date: Nov 1, 2007
Author: David Bradley
MRI brain scans have been used to calibrate and corroborate the results of a new eye-scanning technique that can diagnose multiple sclerosis in a few minutes. The technique, optical coherence tomography (OCT), scans the layers of nerve fibres in the retina to reveal nerve damage associated with the disease. The quick test will ultimately complement more detailed MRI studies of the brain should nerve damage be found.

Cerebral sounds
Date: Oct 1, 2007
Author: David Bradley
Researchers have used functional MRI to locate the part of the brain responsible for constructing the "sound space" that allows us to locate the position of a particular noise. The results confirm the findings of an earlier controversial study of the planum temporale.

Current status of functional MRI on small animals: application to physiology, pathophysiology, and cognition
Date: Aug 16, 2007
Author:
This review aims to make the reader aware of the potential of functional MRI in brain activation studies in small animal models. As small animals generally require anaesthesia for immobilization during MRI protocols, this is believed to be a serious limitation to the type of question that can be addressed with fMRI.

You say placebo
Date: Aug 1, 2007
Author: David Bradley
Functional magnetic resonance imaging (fMRI) combined with positron emission tomography (PET) could give medicine an answer to one of its most vexing questions - Why do placebos make some people well and leave others unaffected or feeling worse?

Date: Jul 19, 2007
Author:
This article reviews the techniques and clinical applications of functional MRI (fMRI) of the female pelvis, including cine MRI, diffusion-weighted MRI (DWI), and dynamic contrast-enhanced (DCE)-MRI.

Master and commander: the far side of reason
Date: Jul 1, 2007
Author: David Bradley
fMRI has revealed that there are two, rather than one, commander in the brain controlling our voluntary actions, according to US neuroscientists. Their work could help improve our understanding of problems associated with brain injury.
