Eye test betters MRI in stroke
Date: Oct 1, 2009
Author: David Bradley
US researchers have demonstrated proof of principle that a short and simple assessment of eye movements in suspected stroke patients can distinguish new strokes from other less serious disorders better than magnetic resonance imaging. The technique demonstrated only in a small-scale study could help screen patients complaining of dizziness, nausea, and spinning sensations.

1H NMR metabolomics study of age profiling in children
Date: Sep 28, 2009
Author:
Metabolic profiling of urine provides a fingerprint of personalized endogenous metabolite markers that correlate to a number of factors such as gender, disease, diet, toxicity, medication, and age. In this study, age-related metabolic changes in children of age 12 years and below were analyzed by 1H NMR spectroscopy of urine. These results may be potentially useful in assessing the biological age (as opposed to chronological) of young humans as well as in providing a deeper understanding of the confounding...

Tears and smiles bond secure mothers to baby
Date: Sep 1, 2009
Author: David Bradley
The sight of her baby's smile or even its tears cause the reward centres in a mother's brain to light up, according to an international functional magnetic resonance imaging (fMRI) study, but only if the mother herself had a secure attachment to her own parent.

In ovo non-invasive quantification of the myocardial function and mass of chick embryos using magnetic resonance imaging
Date: Aug 14, 2009
Author:
Though, the chick embryo has long been used as a model for cardiovascular research, MRI has not yet been used for in vivo cardiac studies. This study used retrospectively gated Cine MRI to image the cardiac function of chick embryos in ovo, thus eliminating the need for ECG and respiratory gating The images were then analysed to quantify left ventricular functional parameters and mass.

Influenza on the brain
Date: Aug 1, 2009
Author: David Bradley
A study of children infected by H1N1 influenza, also known as swine flu, highlighted by the US Center for Disease Control used MRI and other scanning techniques to determine what brain complications may have occurred during the progression of the disease.

Aging effects on human calf muscle properties assessed by MRI at 3 Tesla
Date: Jul 28, 2009
Author:
The purposes of this study was to determine age-related changes in MR properties as T2 and T2* relaxation times, fat content, and magnetization transfer in the human calf, and comparison of these effects in different muscle groups.

Brain surgery uncut
Date: Jul 1, 2009
Author: David Bradley
A new approach to brain surgery avoids the use of the surgeon's scalpel and instead exploits advances in magnetic resonance imaging to guide an ultrasound intervention.

MRSI and DTI: a multimodal approach for improved detection of white matter abnormalities in alcohol and nicotine dependence
Date: Jun 24, 2009
Author:
The primary goal of this study was to determine if abnormalities of 1H MRSI derived metabolite concentrations were apparent in those brain regions that also showed microstructural abnormalities by diffusion tensor imaging in two similar cohorts of alcohol dependent individuals.

Nosologic imaging of the brain: segmentation and classification using MRI and MRSI
Date: May 27, 2009
Author:
A new technique is presented to create nosologic images of the brain using MRI and MRSI data. A nosologic image summarizes the presence of different tissues and lesions in a single image by color coding each voxel or pixel according to the histopathological class it is assigned to. The proposed technique applies advanced methods from image processing and pattern recognition to seqment and classify brain tumors, thereby representing tumor heterogeneity and class probabilities, which may help clinicians in...
