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.
Read MoreJournal 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.
Read MoreMagnetic fields: Memory effects
Date: Sep 1, 2012
Author: David Bradley
Concerns about the effects on healthcare professional, maintenance and engineering staff and evening cleaners have been raised with regards to exposure to the strong magnetic fields generated by MRI instruments.
Read MoreJournal 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.
Read MoreMS 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.
Read MoreJournal Highlight: Ex vivo diffusion tensor MRI of human hearts: Relative effects of specimen decomposition
Date: Jul 23, 2012
Author: spectroscopyNOW
The ability to reconstruct local fiber orientation within a unique set of human hearts using diffusion tensor MRI is described.
Read MoreStem 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.
Read MoreJournal 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.
Read MoreOld 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.
Read MoreJournal 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.
