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.

Talking music: fMRI improvises a link

Date: Mar 1, 2014

Author: David Bradley

Functional magnetic resonance imaging (fMRI) of the brains of jazz musicians engrossed in spontaneous, improvisational musical conversation light up in areas conventionally associated with spoken language and syntax. These brain regions are thought to be involved in the interpretation of the structure of phrases and sentences. Conversely, the musical "conversation" leads to reduced activity in brain areas linked to meaning, semantics, - those processes that work out the meaning of spoken language.

Journal Highlight: Functional connectivity magnetic resonance imaging in stroke: an evidence-based clinical review

Date: Feb 24, 2014

Author: spectroscopyNOW

This review provides an up-to-date summary of the available scientific data evaluating the clinical application of functional connectivity magnetic resonance imaging among stroke survivors.

Hear, hear: MRI offers acoustic neuroma insights

Date: Feb 1, 2014

Author: David Bradley

For the first time, a US research team has demonstrated, using magnetic resonance imaging data, that taking regular aspirin reduces the growth of acoustic neuromas, also known as vestibular schwannomas. The development of this type of intracranial tumour can lead to tinnitus and hearing loss but can also be fatal.

Journal Highlight: Diagnostic and prognostic value of MRI T2 quantification in heart transplant patients

Date: Jan 27, 2014

Author: spectroscopyNOW

This study was designed retrospectively to assess the value of myocardial T2 to detect or predict ongoing acute heart rejection, in heart transplant patients, with a 1.5-T MRI magnet.

Counting on brain structure: MRI reveals numeracy

Date: Jan 1, 2014

Author: David Bradley

Magnetic resonance image can reveal whether an individual's numeracy skills pivot on their spatial or non-spatial awareness skills, according to researchers in The Netherlands and Germany writing in the Journal of  Cognitive Neuroscience.

Journal Highlight: Diffusion MRI in the diagnosis of parkinsonism and tremor

Date: Dec 13, 2013

Author: spectroscopyNOW

The advantages of diffusion MRI over conventional MRI for differentiating patients with Parkinson’s disease, atypical parkinsonian disorders and essential tremor are discussed.
