Sharp Increase for CT, MRI Tests

U.S. patients are getting a lot more high-tech imaging tests, a study has found. The study covered 377,000 people across a 10-year period. All were part of a managed care organization. Use of computed tomography (CT) scans doubled in 10 years. Magnetic resonance imaging (MRI) tests tripled. These images did not replace older tests. Rather, they were added to these tests. The study appeared in the journal Health Affairs. Reuters Health news service wrote about it November 10.
