Abstract
When a patient in Altoona, Pa., needs an emergency brain scan in the middle of the night, a doctor in Bangalore, India, is asked to interpret the results. Spurred by a shortage of U.S. radiologists and an exploding demand for more sophisticated scans to diagnose scores of ailments, doctors at Altoona Hospital and dozens of other American hospitals are finding that offshore outsourcing works even in medicine. . . . Most of the doctors are U.S.-trained and licensed — although there is at least one experiment using radiologists without U.S. training.
