Abstract
SUMMARY
OncologySTAT Editorial Team
Medical use of computed tomography (CT) has increased in recent years. CT delivers a higher radiation dosage than conventional diagnostic radiography, by some estimates equivalent to the range of radiation exposure observed among long-term survivors of the Hiroshima and Nagasaki atomic bombs (10 to 100 millisieverts [mSV]). Exposure to ionizing radiation at doses used in common CT scans has been shown to increase the risk of cancer. This study estimated the level and variability of radiation exposure,...
