CT scanning lung cancer. University of South Florida clinical trial of 50,000 smokers was carried out to compare the effectiveness of CT scans with X-rays for detecting lung cancer. (Today's Tomorrows Fall 2002.) Each participating smoker was randomly assigned to one of two screening methods, CT or chest X-ray, and the age (in years) at which the scanning method first detects a tumor was to be determined. One goal of the study is to compare the mean ages when cancer is first detected of the two screening methods.
