Journal Highlight: Breast cancer subtype intertumor heterogeneity: MRI-based features predict results of a genomic assay

Date: Dec 21, 2015

Author: spectroscopyNOW

The association between a validated, gene-expression-based, aggressiveness assay, Oncotype Dx RS, and morphological and texture-based image features extracted from magnetic resonance imaging has been investigated.

Happiness is in the MRI of the beholder

Date: Dec 1, 2015

Author: David Bradley

Researchers in Japan have used magnetic resonance imaging and a questionnaire to reveal a correlation between the size of a structure in the brain known as the precuneus and whether or not a person describes themselves as happy.

Journal Highlight: Magnetic resonance imaging of ionic currents in solution: The effect of magnetohydrodynamic flow

Date: Nov 23, 2015

Author: spectroscopyNOW

The magnetohydrodynamic mechanism for ionic volume currents in a magnetic field, which predicts a slow evolution of signals, has been tested to help explain neural activity.

Anyone who had a heart: MRI reveals gender gap

Date: Nov 1, 2015

Author: David Bradley

As we get older the left ventricle of the heart responds differently in men and women in terms of its overall mass and volume and how that changes. For both, there is increased concentric remodelling of this tissue with age but for men, magnetic resonance imaging (MRI) reveals changes with implications for long-term heart health, which highlights the importance of research into changes in the aging heart and using different approaches to study.

Journal Highlight: MRI accurately identifies early murine mammary cancers and reliably differentiates between in situ and invasive cancer: correlation of MRI with histology

Date: Oct 19, 2015

Author: spectroscopyNOW

Precise MRI–histology correlation demonstrates that MRI reliably detects early in situ cancer and differentiates in situ from invasive cancers in the SV40Tag mouse model of human breast cancer.

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.
