Metastatic detection: MRI nano-tracking
Date: Oct 1, 2012
Author: David Bradley
Fluorescence molecular tomography and magnetic resonance imaging can exploit new nanotechnology to facilitate the identification of metastatic breast cancer cells before they grow into untreatable tumours. The work might eventually reduce the mortality rates in this disease.

Journal Highlight: Use of MRI and CT for fat imaging in children and youth: what have we learned about obesity, fat distribution and metabolic disease risk?
Date: Sep 24, 2012
Author: spectroscopyNOW
This review on childhood obesity examines the existing literature on visceral and subcutaneous abdominal, intrahepatic and intramuscular fat and emphasises the importance of imaging techniques like MRI and CT in their study.

Journal Highlight: Real-time phase-contrast MRI of cardiovascular blood flow using undersampled radial fast low-angle shot and nonlinear inverse reconstruction
Date: Aug 27, 2012
Author: spectroscopyNOW
A new method for real-time phase-contrast MRI combines flow-encoding gradients with highly undersampled radial fast low-angle shot acquisitions and phase-sensitive image reconstructions by regularized nonlinear inversion.

MS disability progression: Drug impact
Date: Aug 1, 2012
Author: David Bradley
For almost two decades beta-interferons, a type of protein involved in the immune response, have been prescribed to patients with multiple sclerosis (MS). However, a new study indicates that they may actually have no measurable impact on the long-term disability progression in the disease.

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.
