Influenza on the brain
Date: Aug 1, 2009
Author: David Bradley
A study of children infected by H1N1 influenza, also known as swine flu, highlighted by the US Center for Disease Control used MRI and other scanning techniques to determine what brain complications may have occurred during the progression of the disease.

Aging effects on human calf muscle properties assessed by MRI at 3 Tesla
Date: Jul 28, 2009
Author:
The purposes of this study was to determine age-related changes in MR properties as T2 and T2* relaxation times, fat content, and magnetization transfer in the human calf, and comparison of these effects in different muscle groups.

Brain surgery uncut
Date: Jul 1, 2009
Author: David Bradley
A new approach to brain surgery avoids the use of the surgeon's scalpel and instead exploits advances in magnetic resonance imaging to guide an ultrasound intervention.

MRSI and DTI: a multimodal approach for improved detection of white matter abnormalities in alcohol and nicotine dependence
Date: Jun 24, 2009
Author:
The primary goal of this study was to determine if abnormalities of 1H MRSI derived metabolite concentrations were apparent in those brain regions that also showed microstructural abnormalities by diffusion tensor imaging in two similar cohorts of alcohol dependent individuals.

Nosologic imaging of the brain: segmentation and classification using MRI and MRSI
Date: May 27, 2009
Author:
A new technique is presented to create nosologic images of the brain using MRI and MRSI data. A nosologic image summarizes the presence of different tissues and lesions in a single image by color coding each voxel or pixel according to the histopathological class it is assigned to. The proposed technique applies advanced methods from image processing and pattern recognition to seqment and classify brain tumors, thereby representing tumor heterogeneity and class probabilities, which may help clinicians in...

Image avoidance
Date: May 1, 2009
Author: David Bradley
Efforts should be made to avoid unnecessary patient exposure to imaging devices that use ionising radiation, according to a warning from the International Atomic Energy Agency. The Agency suggests that MRI and ultrasound should therefore be more widely used instead of X-ray based imaging.

Palmar bowing of the flexor retinaculum on wrist MRI correlates with subjective reports of pain in carpal tunnel syndrome
Date: Apr 30, 2009
Author:
The pupose of this study was to investigate the utility of palmar bowing of the flexor retinaculum on magnetic resonance imaging as an adjunct to presurgical evaluation of carpal tunnel syndrome.

Depressing brain scans
Date: Apr 1, 2009
Author: David Bradley
The first study of its kind has used MRI to demonstrate how changes in cortical thickness may surprisingly relate brain structure to clinical depression. The large-scale US study suggests that a thinning of the right hemisphere of the brain could be a risk factor for depression.

Neuroimaging assessment of memory-related brain structures in a rat model of acute space-like radiation
Date: Mar 24, 2009
Author:
The pupose of this study was to investigate the acute effects on the central nervous system (CNS) of 56Fe radiation, a component of high-energy charged particles (HZE) in space radiation, using quantitative magnetic resonance imaging (MRI) noninvasively.
