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.

Assessment of metabolic changes in the striatum of a rat model of parkinsonism: an in vivo 1H MRS study
Date: Feb 24, 2009
Author:
Degeneration of the dopaminergic neurons of the substantia nigra pars compacta in Parkinson's disease induces an abnormal activation of the glutamatergic neurotransmission system within the basal ganglia network and related structures. The aim of this study was to use proton MRS to show metabolic changes in the striatum of 6-hydroxydopamine-lesioned rats, a rodent animal model of Parkinson's disease.

Nano MRI
Date: Feb 1, 2009
Author: David Bradley
Researchers at IBM working with a team at Stanford University have demonstrated MRI with a volume resolution 100 million times better than possible conventional systems. The technology could herald single-cell MRI.

Crime and punishment
Date: Jan 1, 2009
Author: David Bradley
A truly interdisciplinary collaboration between biology, law and neuroscience at Vanderbilt University has used functional magnetic resonance imaging fMRI to watch how the brain changes when a person thinks about crime and punishment.

Monitoring response to chemotherapy of non-Hodgkin's lymphoma xenografts by T2-weighted and diffusion-weighted MRI
Date: Dec 18, 2008
Author:
An effective method for in vivo detection of early therapeutic response of patients with non-Hodgkin's lymphoma would enable personalized clinical management of cancer therapy and facilitate the design of optimal treatment regimens. This study evaluates the feasibility of T2-weighted MRI and diffusion-weighted MRI for in vivo detection of response of human diffuse large B-cell lymphoma xenografts in severe combined immunodeficient mice to chemotherapy.
