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.
Read MoreNeuroArm, 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.
Read MoreHead and neck imaging: The role of CT and MRI
Date: Apr 18, 2007

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.
Read MoreQuantitative 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.

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.
Read MoreIn-depth study of the electromagnetics of ultrahigh-field MRI
Date: Feb 22, 2007
Author:
In this paper, numerical and experimental studies of the TEM resonator modes at ultrahigh-field MRI are performed using an in-house finite difference time domain package at 340 MHz and using an 8 T whole-body MRI system.
Read MoreThe brain gain
Date: Jan 26, 2007
Author: David Bradley
US researchers used fMRI to probe brain activity associated with potential monetary gains and losses. They certain regions are more sensitive when you are heading for the red than when you are in the black, providing clues to how gambling addiction and other behavioural problems might be studied.
Read MoreItchy and scratchy
Date: Jan 1, 2007
Author: David Bradley
Researchers are only just begin to scratch the surface of the brain with functional MRI. Now, a study of perception in both allergen- and histamine-induced itch has revealed how different parts of the brain are activated in response to stimulation from each type.
