Pinpointing prostate problems without surgery
Date: Feb 15, 2010
Author: David Bradley
Magnetic resonance spectroscopy, the molecular cousin of MRI could be used to pinpoint the exact location of prostate cancers and to determine the aggressiveness of a tumour, according to research published in the Science Translational Medicine. The approach could help guide treatment.

Red lenses
Date: Feb 1, 2010
Author: David Bradley
US scientists have used MRI to show that apparently the less you use your brain's frontal lobes, the more you perceive your behaviour through rose-tinted spectacles. They publish details in the February issue of the journal NeuroImage.

MRS of the occipital cortex and the cerebellar vermis distinguishes individual cats affected with alpha-mannosidosis from normal cats
Date: Jan 25, 2010
Author:
In vivo MRS from the cerebellar vermis and occipital cortex of cats with alpha mannosidosis (AMD) demonstrated a broad signal between 3.4 - 4.3 ppm (arrowed) from undigested oligosaccharides, which was not observed in normal cats. High-resolution NMR spectra of perchloric acid extracts confirmed the presence of accumulated oligosaccharides along with increased resonances from Glc-NAc and anomeric sugar protons in tissues from AMD cats. This characteristic MRS pattern may be used for diagnosis and treatment...

MRI nanoparticles seek and destroy cancer cells
Date: Jan 1, 2010
Author: David Bradley
A single nanoparticle can be tracked using real-time MRI as it homes in on cancer cells. A fluorescent dye used to tag the nanoparticle couples with heat therapy to kill the targeted cells.

Diffusion tensor imaging of the human calf muscle
Date: Dec 22, 2009
Author:
Diffusion tensor imaging can display diffusional anisotropy of tissue. Possibly, proton diffusivity within the highly ordered musculature will change with muscle length since the cross sectional area of the muscle increases with shortening. Results show that the fractional anisotropy significantly decreases and the mean diffusion increases with muscle shortening.

MRI reveals BMI as bogus heart health indicator
Date: Dec 1, 2009
Author: David Bradley
Body mass index, BMI, is not a reliable indicator of overall fitness for obese individuals as assessed by internal, or visceral, fat. An MRI and NMR study reveals that fat accumulation in different parts of the body, such as around the heart and the aorta and within the liver, is associated with decreased heart function, but BMI offers no correlation for this problem.

The development of the birdcage resonator: a historical perspective
Date: Nov 24, 2009
Author:
This personal account, taken from the current special 'coils' issue of NMR in Biomedicine, charts the development of the birdcage resonator, covering the historic context of early MRI development.

Juggling matters on the brain
Date: Nov 1, 2009
Author: David Bradley
UK scientists have used magnetic resonance imaging to reveal that learning a complex task like juggling can causes changes in the white matter in the brain. The findings could have implications for developing new approaches to neurodegenerative diseases, such as multiple sclerosis.

Morphology, binding behavior and MR-properties of paramagnetic collagen-binding liposomes
Date: Oct 22, 2009
Author:
Collagen is the major constituent of the extracellular matrix and responsible for maintaining the structural integrity of organs and tissues, and in pathological processes such as atherosclerosis and myocardial infarction. The diagnostics of the latter diseases using MRI could strongly benefit from the use of collagen-specific contrast agents. Read this outstanding paper selected by the Editor-in-Chief of the journal, Contrast Media & Molecular Imaging.
