CHICAGO (Reuters) - More than half of patients receiving abdominal CT scans, an advanced type of X-ray, got them for tests they did not need, exposing them to excess radiation that could raise the long-term risk of cancer, U.S. researchers said on Monday.

The study, presented on Monday at the Radiological Society of North America meeting in Chicago, adds to mounting evidence that Americans are exposed to an increasing amount of radiation from diagnostic imaging exams.

In August, a team at Emory University in Atlanta reported in the New England Journal of Medicine that as many as 4 million Americans a year are exposed to high doses of radiation.
