Cognitive integrity: MRI reveals benefits
Date: Dec 1, 2012
Author:
A study using magnetic resonance imaging (MRI) shows that mental activities like reading and writing can preserve structural integrity in the brains of older people. Details were reported at the annual meeting of the Radiological Society of North America (RSNA).

Mind mapping: White's what matters
Date: Nov 1, 2012
Author: David Bradley
Researchers in Europe have used an advanced MRI technique to build the first atlas of the microstructure of the white-matter of the human brain. The project has the potential to revolutionise neuroscience, medicine and our understanding of the human brain in the coming decade.

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.

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.
