Radiation Cancer Risk Versus Life Expectancy

According to recent article in Radiology published online October 2011 Radiology, 261,193-198.  “The importance of radiation exposure in determining optimal imaging usage is much reduced for patients with markedly reduced life expectancies: Imaging justification and optimization criteria for patients with substantially reduced life expectancies should not necessarily be the same as for those with normal life expectancies.” 

Makes sense - imagine a situation with 75 year old with CAD post stenting discussing risk of cancer developing after coronary CT angiography.  

According to the article For a patient who had been treated with CABG surgery, the estimated reduction in lifetime radiation-associated lung cancer risk was approximately 57% for a 55-year-old patient, versus 12% for a 75-year-old patient.
