Functional magnetic resonance imaging may be more accurate than the polygraph for lie detection

When people lie, they use different parts of their brains than when they tell the truth, and these brain changes can be measured by functional magnetic resonance imaging (fMRI), according to a study presented today at the annual meeting of the Radiological Society of North America.

New non-surgical technique that can help doctors determine when breast cancer has invaded the lymph nodes

A key question after a cancer diagnosis is whether the cancer has spread to nearby lymph nodes. Researchers at the University of Michigan Comprehensive Cancer Center have found a new non-surgical technique that can help doctors determine when breast cancer has invaded the lymph nodes, sparing some women an extra trip to the operating room.
