They consisted of 54 sets each of chest radiographs with- and without simulated nodules.  Each data set contained a standard- and a corresponding dual-energy subtracted chest radiograph (DES image).  The diameter of the simulated nodules was 8-, 10-, and 12 mm; nodules of each size manifested attenuation of -450, -200, and 30 Hounsfield units (HU).  We performed receiver operating characteristic (ROC) analysis to compare the observers’ performance in detecting nodules.\nResults:  For -450 HU nodules the mean area under the ROC curve (AUC) without and with DES images was 0.66 and 0.77, respectively; the difference was significant (paired t-test, p < 0.01).  For nodules with -200- and 30 HU, there was no significant difference in the AUC value (0.79 vs. 0.77, p=0.13; 0.92 vs. 0.94, p=0.17, respectively).\nConclusion:  The addition of DES images to standard chest radiographs improved the performance of radiologists charged with detecting simulated nodules with an attenuation of -450 HU.","subitem_description_type":"Other"}]},"item_16_description_77":{"attribute_name":"URL","attribute_value_mlt":[{"subitem_description":"http://www.springerlink.com/content/kq88067j70104k40/","subitem_description_type":"Other"}]},"item_16_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer"},{"subitem_publisher":"Japan
