Arterial Spin Labelling: MRI reveals brain artery stiffness

Date: Oct 1, 2015

Author: David Bradley

Arterial spin labelling MRI can be used non-invasively to measure vascular compliance, or how stiff an artery is, in the human brain, offering a new way to monitor brain health in patients at risk of stroke and in the early diagnoses of Alzheimer's disease.

Journal Highlight: Acceleration and motion-correction techniques for high-resolution intravascular MRI

Date: Sep 21, 2015

Author: spectroscopyNOW

Compressed sensing reconstruction and ungated motion-compensation using projection shifting have been tested to see if they provide faster motion-suppressed intravascular MRI operation.

Suicidal decision: Relative clues from fMRI

Date: Sep 1, 2015

Author: David Bradley

New clues from neuropsychological and functional magnetic resonance imaging studies (fMRI) in close relatives of suicide completers corroborates the results of a series of studies on a link between risky decision making and suicidal behaviour.

Journal Highlight: The prefrontal dysfunction in individuals with Internet gaming disorder: a meta-analysis of functional magnetic resonance imaging studies

Date: Aug 24, 2015

Author: spectroscopyNOW

61 Candidate articles on functional MRI studies of brain activity of individuals with Internet gaming disorder were reviewed and ten were selected for a comprehensive series of meta-analyses.

Diffusor tensor imaging: Moving water in the Alzheimer's brain

Date: Aug 1, 2015

Author: David Bradley

Microstructural changes in the brain that occur in the fatal neurodegenerative disorder Alzheimer's disease have been detected using diffusion tensor imaging (DTI) magnetic resonance imaging (MRI), which can determine the diffusion of water in the brain.

Journal Highlight: MRI for differentiating primary fallopian tube carcinoma from epithelial ovarian cancer

Date: Jul 20, 2015

Author: spectroscopyNOW

A comparison of the MRI features of primary fallopian tube carcinoma and primary epithelial ovarian cancer has shown that the technique can differentiate between the two conditions.

Parrot fashion: Understanding Monty's mate

Date: Jul 1, 2015

Author: David Bradley

Specialized and behaviorally regulated gene expression has been used to reveal the structural differences in the parrot brain that could explain why these birds are such good mimics. The discovery marks a turning point in almost three and a half decades of research and could lead to new insights into the neural  mechanisms of speech in humans too.

Journal Highlight: The effect of ageing on fMRI: Correction for the confounding effects of vascular reactivity evaluated by joint fMRI and MEG in 335 adults

Date: Jun 22, 2015

Author: spectroscopyNOW

The resting-state fluctuation amplitude in the fMRI signal in neural measurements is modulated by measures of vascular function and is not driven solely by changes in the variance of neural activity.

Examining advertising: Free-range functional MRI clues

Date: Jun 1, 2015

Author: David Bradley

Functional MRI reveals the pattern of brain activation in consumers who are less certain about buying a particular product and hints at who might be more easily swayed by an advertisement.

Journal Highlight: Detection of extracellular matrix degradation in intervertebral disc degeneration by diffusion magnetic resonance spectroscopy

Date: May 25, 2015

Author: spectroscopyNOW

Diffusion magnetic resonance spectroscopy was used to detect the extracellular matrix (ECM) degradation during intervertebral disc degeneration by the increased mobility of ECM macromolecules such as proteoglycans and collagens.
