Anxiety: The pleasure principle

Date: Aug 1, 2014

Author: David Bradley

Functional magnetic resonances imaging (fMRI) reveals activity in two different regions of the brain of people given a choice between two or more equally positive outcomes that give rise to both pleasure and anxiety simultaneously.

Journal Highlight: MRI by steering resonance through space

Date: Jul 21, 2014

Author: spectroscopyNOW

A technique called steering resonance over the object (STEREO) has been developed to excite magnetic resonance signals locally to demonstrate the feasibility of MRI with multidimensional spatiotemporal-encoding that can compensate extreme field inhomogeneity.

Here comes the flood: Functional memory insights

Date: Jul 1, 2014

Author: David Bradley

Many people are familiar with how a simple trigger, a scent, a colour, a piece of music, a photograph can bring back a "flood" of disparate memories all at once. There are mathematical theories called global similarity models that attempt to explain this phenomenon. Now, a functional magnetic resonance study (fMRI) on memory and categorization has put this mathematical model on a firm neurobiological footing for the first time.

Journal Highlight: Does magnetic resonance imaging predict future low back pain? A systematic review

Date: Jun 23, 2014

Author: spectroscopyNOW

MEDLINE, CINAHL and EMBASE databases were searched in a systematic review of the ability of MRI studies of the lumbar spine to predict future lower back pain.

Nano targeting: Self-assembled contrast agents

Date: Jun 1, 2014

Author: David Bradley

The development of self-assembling nanoparticles could allow contrast agents for magnetic resonance imaging to be carried to target sites in the body much more effectively than by other means, according to US researchers.

Journal Highlight: Value of MRI of the hand and the wrist in evaluation of bone age: Preliminary results

Date: May 26, 2014

Author: spectroscopyNOW

Bone age was determined using MRI of the hand and wrist and the data could be useful for developing an atlas of skeletal development and bone age.

MRI implant: Monitoring oxygen levels

Date: May 1, 2014

Author: David Bradley

A solid device that can be implanted in the body could be used to monitor oxygen levels in the body over the course of several seeks by scanning with magnetic resonance imaging (MRI) has  been developed for a wide range of medical diagnostics applications.

Journal Highlight: Improving outcomes of screening breast MRI with practice evolution: Initial clinical experience with 3T compared to 1.5T

Date: Apr 21, 2014

Author: spectroscopyNOW

This report set out to investigate if changing from 1.5T to 3T breast MRI is associated with a change in BI-RADS categories, positive predictive value of biopsy recommendation, or cancer detection rates in high-risk screening breast MRI.

Task or team: Flipping leadership roles

Date: Apr 1, 2014

Author: David Bradley

Functional magnetic resonance imaging (fMRI) shows that activity between two networks within the brain are not activated simultaneously: one network being associated with noticing and working with other people while the other is more task orientated. The findings may have implications for human resource management and in understanding social dynamics.

Journal Highlight: Influence of paramagnetic melanin on the MRI contrast in melanoma: a combined high-field (11.7 T) MRI and EPR study

Date: Mar 24, 2014

Author: spectroscopyNOW

In order to elucidate the possible role of melanin in the MRI contrast of melanoma, the paramagnetic content in melanin pigment was correlated to the contrast on T1-, T2- and T2*-weighted images.
