Summary

The Lung Image Database Consortium (LIDC) image collection consists of diagnostic and lung cancer screening thoracic CT scans with marked-up annotated lesions. It is a web-accessible international resource for development, training, and evaluation of computer-assisted diagnostic (CAD) methods for lung cancer detection and diagnosis. 

The data set hosted in the NCI CBIIT instance of NBIA is a pilot version of the LIDC data set which contains 399 of the total 1,010 patients found in the full data set.  For more information about the final release of the complete LIDC-IDRI data set please visit The Cancer Imaging Archive (TCIA) wiki page on this collection.
