ABSTRACT
PURPOSE:
The purpose of this study was to evaluate the usefulness of single-shot dual-energy subtraction (DES) method using a flat-panel detector for lung cancer screening MATERIALS ANDMETHODS:
The subjects were 13,315 residents (5801 males and 7514 females) aged 50 years or older (50-97 years, with an intermediate value of 68 years) who underwent lung cancer screening for a period of 1 year and 6 months from January 2019 to June 2020. We investigated whether the number of lung cancers detected, the detection rate, and the rate of required scrutiny changed, when DES images were added to the judgment based on conventional chest radiography.RESULTS:
When DES images were added, the number and percentage of cancer detection increased from 16 (0.12%) to 23 (0.17%) (P < 0.05). Five of the newly detected 7 lung cancers were in the early stages of resectable cancer. The rate of participants requiring scrutiny increased slightly from 1.1 to 1.3%.CONCLUSION:
DES method improved the detection of lung cancer in screening. The increase in the percentage of participants requiring scrutiny was negligible.Palabras clave
