To evaluate the effect of temporal subtraction images on the radiologists’ detection of early primary lung cancer in computed tomography (CT) scans. Fourteen cases with primary lung cancer and 16 normal cases were used for this study from a database of low-dose CT images, which were obtained from a lung cancer screening program in Nagano, Japan. Images were obtained with a single-detector helical...
The authors evaluted the usefulness of artificial neural networks (ANNs) in the differential diagnosis of interstitial lung disease.The authors used three-layer, feed-forward ANNs with a back-propagation algorithm. The ANNs were designed to distinguish between 11 interstitial lung diseases on the basis of 10 clinical parameters and 16 radiologic findings extracted by chest radiologists. Thus, the...
