In the staging and treatment of lung cancer, it is important to assess lymph nodes involvement. An accurate labeling of the regions of mediastinal and hilar nodes is essential because it allows to assess treatment outcomes, to select appropriate therapy for patient or to perform clinical trials across institutions, etc .

We provide here the dataset that have been used in the publication [Sarrut 2014, Lynch 2013, Pitson 2012]. This dataset consists on thoracic CT images of five lung cancer patients on which three experts (RL, LC, GP) consensually delineated lymph nodes stations 1 to 11, following the new IASLC stations definition [Rusch et al 2009]. Several anatomical structures (such as Aorta, vessels etc) are also available.
