Thanks to a new study from Columbia Engineering School, doctors may now be able to diagnose in their offices non-periodic arrhythmias-noninvasively and at low cost-within a single heartbeat. (2011-12-09)
Quantitative magnetic resonance imaging measures were associated with prognostic tumor markers, demonstrating the potential of magnetic resonance imaging for prediction of disease prognosis and stratification of patients to appropriate therapies. (2011-12-08)
It's still unclear what's different in the brains of people with autism spectrum disorders (ASDs), but evidence from genetic and cell studies points to abnormalities in how brain cells (neurons) connect to each other. (2011-12-06)
Yale Cancer Center researchers have shown that a tiny genetic variation predicts chances of survival and response to treatment for patients with ovarian cancer. (2011-12-05)
Sustained changes in the region of the brain associated with cognitive function and emotional control were found in young adult men after one week of playing violent video games, according to study results presented by Indiana University School of Medicine researchers at the annual meeting of the Radiological Society of North America. (2011-12-02)
The first study to investigate risk factors for the vascular condition called CCSVI (chronic cerebrospinal venous insufficiency) in volunteers without neurological disease has identified what the researchers call a remarkable similarity between this condition and possible or confirmed risk factors for multiple sclerosis (MS). (2011-12-01)
A functional magnetic resonance imaging (fMRI) analysis of long-term effects of violent video game play on the brain has found changes in brain regions associated with cognitive function and emotional control in young adult men after one week of game play. (2011-11-30)
Findings on coronary CT angiography (CTA), a noninvasive test to assess the coronary arteries for blockages, show different risk scenarios for men and women, according to a study presented today at the Radiological Society of North America (RSNA). (2011-11-30)
In a new study presented today at the annual meeting of the Radiological Society of North America (RSNA), growth hormone replacement for six months was found to increase bone formation in abdominally obese women. (2011-11-29)
Glioblastoma is regarded as the most malignant form of brain tumor. In many cases, neurosurgeons are not able to remove such tumors completely because of the risk of destroying too much brain tissue in the process. (2011-11-28)
A low-calorie diet eliminates insulin dependence and leads to improved heart function in obese patients with type 2 diabetes, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). (2011-11-28)
Using functional magnetic resonance imaging (fMRI), researchers have identified abnormalities in the brains of children with attention deficit/hyperactivity disorder (ADHD) that may serve as a biomarker for the disorder, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). (2011-11-28)
Scientists at the University of California, San Diego School of Medicine and UC San Diego Moores Cancer Center, in collaboration with colleagues in Boston and South Korea, say they have identified a novel gene mutation that causes at least one form of glioblastoma (GBM), the most common type of malignant brain tumor. (2011-11-21)
In the first study using magnetic resonance imaging (MRI) to evaluate cardiovascular risk in World Trade Center (WTC) first responders, researchers from Mount Sinai School of Medicine have found that the responders who experienced high levels of exposure to the initial dust cloud on September 11, 2001, demonstrate high-risk features of atherosclerosis (plaque in arteries).

For patients with non-small cell lung cancer (NSCLC) the accurate determination of the lymph node status before therapy is critical to develop an individualized treatment plan. Research from the October issue of The Journal of Nuclear Medicine highlights a new way for this information to be collected-a virtual fly-through three-dimensional 18F-FDG PET/computed tomography (FDG-PET/CT) bronchoscopy that has high diagnostic accuracy for the detection of regional lymph node metastases.

A combination of an oral drug, called sorafenib, and a method for injecting microbeads of chemotherapy directly into tumors has been proven safe for liver cancer patients and may improve outcomes for those who have these fast-growing, deadly tumors whose numbers are on the rise in the U.S. (2011-10-03)
Most drug therapy interventions for people with autism have targeted psychiatric problems, including aggression, anxiety and obsessive behavior. (2011-09-30)
According to a recent poll of 1,000 American voters conducted for the American College of Radiology, nearly 9-in-10 women reported that having a regular mammogram gave them a feeling of control over their own health care. (2011-09-28)
First results from an international comparison of the care of patients with rectal cancer have shown there are substantial differences in the use of chemotherapy and radiotherapy between European countries. (2011-09-26)
