(A) Manually delineated major lymph node areas of entire body of one patient with labels and (B) delineated lymph node area in one patient (blue lines denote manually contoured LNs, and red lines represent predictions obtained using deep learning): (1) cervical LN area; (2) axillary and mediastinal LN areas; (3) para-aortic LN area; and (4) iliac and presacral LN areas; (5) inguinal LN areas. Abbreviation—LN: Lymph node.

Evaluation results by lymph node area.
(A) Dice similarity coefficient, precision, and recall of evaluation results; (B) Hausdorff 95 (HD95) values from evaluation results (unit: pixel). Abbreviations—DSC: Dice similarity coefficient; HD95: Hausdorff distance 95%.
