ABSTRACT
Objective:
To evaluate the computer aided detection system on the diagnosis of pulmonary nodules.Methods:
120 cases of examined patients with solitary lung nodules up to 9-30 mm in diameter were evaluated. All nodules had been verified by means of biopsy. 120 cases of healthy patients were selected as control group on the basis of confirmation on the chest CT. All chest radiograph in the two group were obtained with a digital radiography system. Five experienced chest radiologists and five residents detected the chest radiograph with or without CAD output images. The scales of performance were evaluated with receiver operating characteristic curve(ROC curve).Results:
The average area under the curve value increased significantly from 0.762 without to 0.825 with CAD output images(P
