New technology targets cancers

Breast-specific gamma imaging (BSGI) is effective in the detection of cancers not found on mammograms or by clinical exam, according to a study.

Stressing the brain

Researchers using functional MRI (fMRI) have determined that the circuitry in the area of the brain responsible for suppressing memory is dysfunctional in patients suffering from stress-related psychiatric disorders.

3-D glimpse of bacterial cell-wall architecture

Bacterial cell walls are actually made up of a thin single layer of carbohydrate chains, linked together by peptides, which wrap around the bacterium.

Anorexia impairs adolescent bone development

Children and teenagers with even mild cases of anorexia exhibit abnormal bone structure, according to a new study appearing in the December issue of Radiology.

Novel imaging technique reveals brain abnormalities

A study reveals shape differences in the brains of children with ADHD, which could help pinpoint the specific neural circuits involved in the disorder.

Predicting multiple sclerosis progression

A new study shows that MRI scans used on multiple sclerosis patients to determine if the disease has affected gray matter in the brain can identify those at-risk for progression of disability.

Computer model improves ultrasound image

A Dutch researcher has developed a computer model that can predict the sound transmission of improved designs for ultrasound instruments.

Breast cancer identification

Three-dimensional (3-D) power Doppler ultrasound helps radiologists distinguish between malignant and benign breast masses, according to a new study.

Identifying cervical cancer early

Using high-resolution magnetic resonance imaging with a special vaginal coil, researchers may be able to identify cervical cancer in its early stages.

The Brain Imaging Centre

Recently, the University of Missouri Department of Psychological Sciences introduced an addition to their field of research with the opening of the Brain Imaging Centre.

Modelling 3D structure of amorphous materials

Researchers have accurately identified tools that model the atomic and void structures of a network-forming elemental material.

Atomic resolution hints at enzyme function

An atomic-resolution view of an enzyme found only in the eye has given researchers clues about how this enzyme, essential to vision, is activated.

Detecting high-risk carotid disease

Canadian researchers have used three-dimensional magnetic resonance imaging to accurately detect bleeding within the walls of diseased carotid arteries, a condition that may lead to a stroke.

Flexible, modular microscope

Life science research and routine applications will benefit from the outstanding flexibility and adaptability brought to the market by the Axio Scope.A1 microscope.

Better diagnosis for focal epilepsy

3T MRI is better at detecting and characterising structural brain abnormalities in patients with focal epilepsy than 1.5T MRI, leading to a better diagnosis and safer treatment of patients.

Study challenges routine use of MRI

A new study suggests women with newly-diagnosed breast cancer who receive an MRI after their diagnosis face delays in starting treatment and are more likely to receive a mastectomy.

When multitasking works best

A new brain imaging study led by a cognitive neuroscientist at the University of New Hampshire finds that there are optimal times when we are better suited to multitask.

PET scans identify mood changes

Brain scans taken at different times of year suggest that the actions of the serotonin transporter-involved in regulating the mood-altering neurotransmitter serotonin-vary by season..

Chronic insomnia linked to cognitive deficits

Cognitive processes related to verbal fluency are compromised in people with insomnia despite the absence of a behavioural deficit.
