Twice as sensitive about matters of the heart

Date: Dec 1, 2006

Author: David Bradley

US researchers have demonstrated that MRI is twice as sensitive as other techniques at detecting early heart damage in patients with the immune system disorder sarcoidosis.

Advances in MR imaging of the skin

Date: Nov 27, 2006

Author:

MR imaging of the skin is challenging because of the small size of the structures to be visualized. This review paper, published in the special issue of NMR in Biomedicine entitled "NMR of the Musculoskeletal System', highlights the recent advances that have been made in this field.

fMRI reveals wider effects of Parkinson's disease

Date: Nov 1, 2006

Author: David Bradley

The common perception of Parkinson's disease is of a disorder that leads to problems with movement, tremors, involuntary spasms, and a shuffling gait. However, functional MRI has now confirmed that the disease can also cause widespread abnormalities in the sense of touch and vision for sufferers. An international team from the US and China presented their findings at the Society for Neuroscience meeting in Atlanta on October 17.

Evaluation of treatment effects in Alzheimer's and other neurodegenerative diseases by MRI and MRS

Date: Oct 23, 2006

Author:

Read this thorough recent evaluation of the treatment effects for neurodegenerative diseases by MRI and MRS taken from the recent special issue of NMR in Biomedicine, entitled "MR and Drug Development".

Nanoparticles sharpen fMRI

Date: Oct 1, 2006

Author: David Bradley

New molecular tools are being developed by researchers at Massachusetts Institute of Technology that will allow functional MRI to make the transition from imaging gross properties of the brain to a fine-tuned analysis based on information flow involving cells and circuits. The new generation of nanoscale calcium contrast agents will have applications in understanding learning, memory, and behaviour, according to the MIT team.

Persistent consciousness?

Date: Sep 12, 2006

Author: David Bradley

Functional MRI has revealed how a patient in a persistent vegetative state seemed capable of understanding and responding to certain commands. The discovery, if proved reproducible in other patients, may lead to a greatly improved understanding of this condition, and perhaps to a novel way of communicating with PVS patients.

Premature diagnosis

Date: Sep 1, 2006

Author: David Bradley

An MRI scan can help in predicting future developmental outcomes of pre-term infants, according to US researchers. The scan reveals abnormalities no picked up by cranial ultrasound and can be used to predict problems that would become apparent by age two years.

Impact of evidence-based medicine on magnetic resonance spectroscopy

Date: Aug 23, 2006

Author:

Magnetic resonance spectroscopy is a robust, non-invasive means of defining aspects of human neurochemistry. After more than two decades, it is clear that in addition to its scientific interest, MRS has diagnostic value in many areas of evidence-based medcine. Read the full paper taken from the recent special issue of NMR in Biomedicine dedicated to clinical MRS.

A mind for politics

Date: Aug 1, 2006

Author: David Bradley

Beware MRI machines if you're a political mole in the candidate's office spying for the other side. Researchers in the US have demonstrated that functional MRI can reveal the differences in brain activity when a political partisan looks at the faces of politicians of different political persuasion. Apparently, cognitive networks in the brain that regulate emotion kick into action when a true blue supporter sees the face of an opposition candidate.

Gd-enhanced MR images of substrates other than water

Date: Jul 25, 2006

Author:

This communication from the new journal, Contrast Media & Molecular Imaging, reports the dramatic relaxation enhancements that can be obtained upon the interaction of substrates like lactate, trifluorolactate and inorganic phosphate with the paramagnetic GdDO3A agent.
