Untreated cavities elevate one’s risk of esophageal and chest infections. Furthermore, dentists often can notice early oral symptoms of eating disorders and systemic illnesses...

"Echocardiograms and nuclear perfusion scanning are the bread and butter of cardiac care," says Dr. Pamela Douglas, chief of cardiovascular medicine at Duke University Medical Center in Durham, N.C., and president of the American College of Cardiology.

MRI is better at telling you how well the heart is pumping, how healthy its walls are and what shape the valves and chambers are in. In other words, says Dr. Edward Martin of the Oklahoma Heart Institute in Tulsa, "MRI has the potential to do everything...
Whatever their specialties, all were teachers. They were growing bone cells and prostate-cancer cells and protein crystals, studying the effect of dust storms on the global climate and space flight on the cardiovascular system.
