Sense and sensibility: Olfaction and anxiety
Date: Oct 1, 2013
Author: David Bradley
US researchers have used functional magnetic resonance imaging (fMRI) to prize open the lid of the olfactory black box and to take a sniff, not at how odour evokes emotions, but at how emotions such as anxiety can "rewire" the brain so that our perception of particular scents changes, perhaps giving the smell of a lover's hair the odour of freshly discarded socks at times of stress.

Journal Highlight: Body MRI artifacts in clinical practice: A physicist's and radiologist's perspective
Date: Sep 23, 2013
Author: spectroscopyNOW
This review promotes understanding of the artifacts which occur in MRI exams due to the high information content, so that they can be prevented or properly interpreted to optimize diagnostic effectiveness.

Explosive model: MRI mathematics pinpoints bombs
Date: Sep 1, 2013
Author: David Bradley
A three-dimensional model of the Earth's crust and the mantle beneath it can be analysed using the same equations as are used to analyse and interpret magnetic resonance data for display of an MRI. Instead of revealing the presence of a brain tumour or damaged tissues following injury the equations can be used to illuminate the material properties of the Earth's interior which can help to reveal the precise locations of explosions across the globe.

Journal Highlight: A pilot functional MRI study of the effects of prefrontal rTMS on pain perception
Date: Aug 26, 2013
Author: spectroscopyNOW
This exploratory pilot study used functional magnetic resonance imaging to examine the effects of left prefrontal repetitive transcranial magnetic stimulation on brain activity and pain perception.

Heads up: American football collision course
Date: Aug 1, 2013
Author: David Bradley
A new measure of the effects of cranial impact in American football players can be used in conjunction with magnetic resonance imaging (MRI) and neurological testing to assess the cumulative effect on players before and after the American football season.

Journal Highlight: Inorganic nanocrystals as contrast agents in MRI: synthesis, coating and introduction of multifunctionality
Date: Jul 22, 2013
Author: spectroscopyNOW
Methods to synthesize inorganic nanocrystals and make them biocompatible and active for MRI are reviewed, with examples of the various approaches and efforts to make them multifunctional.

Back to basics: MRI reveals spinal infection
Date: Jul 1, 2013
Author: David Bradley
Steroids are often injected into sites along the spinal column in treating back pain, but if a batch is contaminated serious infection can arise. Researchers have demonstrated that magnetic resonance imaging (MRI) at the site of injection could be used to identify fungal spinal or paraspinal infection

Journal Highlight: DCE-MRI: a review and applications in veterinary oncology
Date: Jun 24, 2013
Author: spectroscopyNOW
This review summarises the derivation of the models developed to assess dynamic contrast enhanced magnetic resonance imaging (DCE-MRI), its applications to the study and treatment of human and animal cancer, and challenges in reproducibility.

Aging enzyme: MRI reveals depressing link
Date: Jun 1, 2013
Author: David Bradley
Magnetic resonance imaging has revealed a possible protective role for the enzyme telomerase in processes associated with the development of depression in aging patients. The study investigated untreated, depressed participants and found that the size of the hippocampus, a brain structure that is critical for learning and memory, was associated with the amount of telomerase activity measured in the white blood cells.

Journal Highlight: 3T-MRI analysis of epidermis and dermis moisturizing using the T2-mapping sequence
Date: May 20, 2013
Author: spectroscopyNOW
T2-mapping in MRI has been applied to assess basal free water content of the epidermis and dermis and to search for an increase in free water content after applying a moisturizing cream.
