      ). For example, imaging expenditure per Medicare beneficiary increased 85%, outstripping a 34% relative growth in fees for evaluation and management between 2000 and 2009. Factors contributing to the increased use of imaging include advances in technology, expanded clinical indications, an aging population, and increased availability.
