Small vessels near hilum are not guaranteed to be excluded. Collapsed lung may be excluded in some scans. Regions of tumor or collapsed lung that are excluded from training and test data will be masked out during evaluation, such that scores are affected by segmentation choices in those regions.\r\n<h4>Spinal cord<\/h4>\r\n<strong>Standard name:<\/strong>\u00a0SpinalCord\r\n\r\n<strong>RTOG Atlas description:<\/strong>\u00a0The spinal cord will be contoured based on the bony limits of the spinal canal.
