Computer-Aided System Detects Missed Lung Cancer

TUESDAY, June 30 (HealthDay News) -- In lung cancer patients, a computer-aided detection system may detect nodules in chest radiography that were initially overlooked by a radiologist, according to a study published in the July issue of Radiology.

Charles S. White, M.D., of the University of Maryland School of Medicine in Baltimore, and colleagues evaluated chest radiographs from 3,100 patients and found missed cancer on 114 radiographs from 89 patients, with lesion sizes ranging from 0.4 to 5.5 cm.

After each radiograph with a missed lesion was analyzed by the computer-aided detection system, the researchers found that the system correctly identified 53 (47 percent) of undetected lesions on a per-image basis and 46 (52 percent) of undetected lesions on a per-patient basis.

"A significant correlation was found between nodule detection by the computer-aided detection system and the subtlety score, a qualitative measure of conspicuity," the authors conclude. "Further work is necessary to determine the value of computer-aided detection to detect missed lung cancer in the clinical setting."

This study was supported by Riverain Medical; one author reported a financial relationship with the company.
