The dose of radiation used in some chest CT examinations could be cut by half without compromising the radiologist's ability to make a diagnosis, US researchers report in the American Journal of Roentgenology (August). James Ravenel and colleagues from SUNY Upstate Medical University in Syracuse, New York, took CT images of 10 patients using six different radiation levels. When the resulting images were examined blind by five radiologists, they could not tell the difference between images taken with the standard radiographic dose of 280 mAs (equivalent to 600 mrem) and those taken at 160 mAs (340 mrem).
