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?

Functional MR imaging of the female pelvis

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.

Pinpointing additional tumours

Date: Jun 1, 2007

Author: David Bradley

MRI can reveal additional malignancies in one out of every ten breast cancer patients, according to a US study. The data suggest that breast MRI may have a role in the staging evaluation of newly diagnosed breast cancers.

NeuroArm, a new weapon in surgery

Date: May 1, 2007

Author: David Bradley

A surgical robot that carries out its own MRI scans has been created by neurosurgeons in Canada. The system will liberate surgeons from the limitations of the human hand and could extend the working life of experienced surgeons way beyond the first signs of shakiness.

Unchained MRI

Date: Apr 1, 2007

Author: David Bradley

Physicists in Canada have used a conventional MRI system to control the movement of a small metal bead inside a blood vessel. The demonstration could herald the emergence of a new form of surgery that uses MRI to control "untethered" devices within the body.

Quantitative MRI-pathology correlations of brain white matter lesions developing in a non-human primate model of multiple sclerosis

Date: Mar 16, 2007

Author:

Experimental autoimmune encephalomyelitis (EAE) induced with recombinant human myelin/oligodendrocyte glycoprotein in the common marmoset is a useful preclinical model of multiple sclerosis in which white matter lesions can be well visualized with MRI.

Revelationary imaging

Date: Mar 1, 2007

Author: David Bradley

fMRI can reveal your secret intentions. The discovery will not lead us to the pre-emptive crime fighting world of feature film Minority Report, but offers hope for victims of paralysis whose intentions might one day be turned into actions using fMRI and a suitable output device.
