Stem cell tracker: MRI nano tags

Date: Jul 1, 2012

Author: David Bradley

UK researchers have used photothermal microscopy to study how nanoparticles interact with stem cells and how they might best be exploited in tracking the movements of these cells using MRI.

Journal Highlight: Two anatomic resources of canine pelvic limb muscles based on CT and MRI

Date: Jun 25, 2012

Author: spectroscopyNOW

A diagnostic atlas of pelvic limb muscles to facilitate interpretation of MR images of patients with muscle injury and a 3D model of the canine pelvic limb musculature to facilitate anatomic learning have been created.

Old brains, new tricks: Rewiring the elderly

Date: Jun 1, 2012

Author: David Bradley

Conventional wisdom has it that after major "rewiring" work during adolescence, the connections between neurones and groups of neurons remain fixed as we get older. However, evidence is emerging from a variety of sources to suggest that even the aged adult brain has plenty of plasticity and can adapt to accommodate novel sensory experiences.

Journal Highlight: Physics of MRI: A primer

Date: May 21, 2012

Author: spectroscopyNOW

A non-mathematical conceptual approach is presented for understanding magnetic resonance image formation from an intuitive perspective. It is based on an introductory lecture given for the past many years during the "MR Physics and Techniques for Clinicians" course at the Annual Meeting of the ISMRM.

Brain reboot: Anaesthetic awakening

Date: May 1, 2012

Author: David Bradley

A new imaging study has demonstrated how the lower, more primitive part of the brain seem to pull consciousness up by its bootstraps, almost as a computer "boots" before the graphical user interface that is full self-awareness produced by the higher parts of the brain are initiated.

Journal Highlight: Iron deposition in pain-regulatory nuclei in episodic migraine and chronic daily headache by MRI

Date: Apr 23, 2012

Author: spectroscopyNOW

Magnetic resonance imaging findings of iron accumulation in the brain, especially in periaqueductal gray and red nucleus, have been correlated with both duration of illness and frequency of attacks.

Scan your battery with MRI: Charging up an insider view

Date: Apr 1, 2012

Author: David Bradley

A UK-US collaboration has exploited the power of magnetic resonance imaging to take a diagnostic look at one of the perennial problems of modern technology: the chemistry of rechargeable batteries.

Journal Highlight: Predicting long-term survival and treatment response in breast cancer patients receiving neoadjuvant chemotherapy by MR metabolic profiling

Date: Mar 19, 2012

Author:

This study aimed to evaluate whether MR metabolic profiling can be used for prediction of long-term survival and monitoring of treatment response in locally advanced breast cancer patients during neoadjuvant chemotherapy (NAC).

MRI reads early signs: Dyslexia diagnosis

Date: Feb 1, 2012

Author: David Bradley

Children at risk of dyslexia show differences in brain activity on magnetic resonance imaging scans even before they start to learn to read, a study at the Children's Hospital Boston has found.

Journal Highlight: The differences in neural network activity between methamphetamine abusers and healthy subjects performing an emotion-matching task: functional MRI study

Date: Jan 11, 2012

Author:

Methamphetamine (MA) abusers commonly exhibit socially problematic behaviors, such as diminished empathy, decreased emotional regulation and interpersonal violence, which may be attributable to alterations in emotional experience. However, few studies have used functional MRI to examine directly the emotional experience of threatening or fearful non-face images in MA abusers. This study investigates possible differences in neural correlates of negative emotional experiences between abstinent MA abusers and...
