Study reveals drivers of MRI and CT scan utilization in U.S. and CanadaIn a study published in the Journal of the American College of Radiology, scientists recently reported that the use of imaging tests on elderly stroke patients may be affected by age and treatment capacity at any given facility. The assessments they evaluated included magnetic resonance imaging (MRI) and computed tomography (CT) scans, which represent a major component of healthcare expenditure growth.

Lead author Max P. Rosen and his colleagues reported that these tests have been linked to greater life expectancy and declines in rates of cancer mortality. The team explained that a major driver of utilization may be enhanced imaging capacity available at many metropolitan areas around the country.

They analyzed data from a sample of 1,918 American patients and 1,759 Canadian patients, and found that patient age and country were significant predictors for the use of MRI and CT.

"We analyzed the effect of differential capacity on the imaging workup of patients with acute non-hemorraghic stroke," Rosen explained. "Our study demonstrates that for patients presenting with symptoms of acute stroke, differences in scanning capacity may shape aspects of clinical management."
