Findings suggest important differences among smokers in brain responses that underlie the smoking habit

Not all smokers are alike when it comes to cravings, and a new study conducted by researchers at Duke University Medical Center suggests the difference may lie in their brains' sensitivity to drug cues.

Treatment options for skull base tumors

It is estimated that in 2000, more than 359,000 persons were living with a diagnosis of a primary brain tumor in the United States. In 2005, it is estimated that nearly 12,800 deaths will be associated with malignant tumors of the brain and other parts of the central nervous system. Brain tumors are the leading cause of cancer-related deaths in children age 19 and younger.

Researchers use PET/CT for molecular imaging of the heart

For the first time, researchers used positron emission tomography (PET)/computed tomography (CT) for imaging the subcellar function of the heart - from its subcellular function to its morphologic appearance. The results of the study were reported at the Society of Nuclear Medicine's 52nd Annual Meeting June 18–22 in Toronto.
