Deep Learning Assists in Detecting Malignant Lung Cancers (2 of 2) (IMAGE)
Caption
Images in 70-year-old woman with primary adenocarcinoma. (a-c) Posteroanterior (PA) digital chest radiographs. (a) Ground-truth mass (yellow circle) is located in the right middle lung zone. (b) Reader 11 (orange circle) and reader 12 (green circle) marked false-positive regions of interest (ROIs) in the left retrocardiac space instead of the true lesion. Reader 10 initially interpreted this image as normal. (c) With deep convolutional neural network (DCNN) software assistance (dotted circle), all three readers could correctly identify the true nodule in the right lung and abandon their false-positive ROIs. (d) Coronal reconstructed CT image obtained the following day shows a 25-mm mass in the right upper lobe (arrow).
