Magnetic resonance imaging (MRI) is an imaging technique which physicians use for the diagnosis and treatment of medical conditions.

Hippocampal size linked to illness severity, functioning in schizophrenia

Results from an Italian study show that greater hippocampal deflation is associated with increased illness severity and poorer social functioning in patients with schizophrenia.

New analysis on global trends in medical imaging for cardiology applications

The promise of cost and clinical benefits are spurring the penetration of imaging modalities in cardiac applications. While demographics are favouring market growth, cardiac imaging device manufacturers will have to focus on innovative, patient-friendly products that promote greater safety and easier operability.

Fructose linked to food-seeking behavior and food intake

In a study examining possible factors regarding the associations between fructose consumption and weight gain, brain magnetic resonance imaging of study participants indicated that ingestion of glucose but not fructose reduced cerebral blood flow and activity in brain regions that regulate appetite, and ingestion of glucose but not fructose produced increased ratings of satiety and fullness, according to a preliminary study published in the January 2 issue of JAMA.

Stent placement ‘effective alternative to IVT in stroke patients’

In stroke patients in whom intravenous thrombolysis is either contraindicated or has failed, intra-arterial revascularization with cerebral angioplasty and stent placement is an effective and well-tolerated treatment, say Czech researchers.

Measurement of IQ by a singular, standardized test is misleading, finds study

After conducting the largest online intelligence study on record, a Western University-led research team has concluded that the notion of measuring one's intelligence quotient or IQ by a singular, standardized test is highly misleading.

Study provides clear understanding of how the brain organizes visual input

Our eyes may be our window to the world, but how do we make sense of the thousands of images that flood our retinas each day? Scientists at the University of California, Berkeley, have found that the brain is wired to put in order all the categories of objects and actions that we see. They have created the first interactive map of how the brain organizes these groupings.

Advanced MRI can non-invasively evaluate cellular proliferation of tumor models of breast cancer

Scientists at the University of Arizona Cancer Center and the Moffitt Cancer Center, led by Dr. Robert Gillies, have demonstrated that an advanced magnetic resonance imaging (MRI) method can non-invasively evaluate the cellular proliferation of tumor models of breast cancer.
