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.

Early ID for AD

Date: Jun 1, 2009

Author: David Bradley

New software for the automated analysis of MRI brain scans could help specialists identify cases of mild cognitive impairment years before full-blown Alzheimer's disease is apparent, according to US researchers.

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...

Image avoidance

Date: May 1, 2009

Author: David Bradley

Efforts should be made to avoid unnecessary patient exposure to imaging devices that use ionising radiation, according to a warning from the International Atomic Energy Agency. The Agency suggests that MRI and ultrasound should therefore be more widely used instead of X-ray based imaging.

Palmar bowing of the flexor retinaculum on wrist MRI correlates with subjective reports of pain in carpal tunnel syndrome

Date: Apr 30, 2009

Author:

The pupose of this study was to investigate the utility of palmar bowing of the flexor retinaculum on magnetic resonance imaging as an adjunct to presurgical evaluation of carpal tunnel syndrome.
