This collection contains 26 cases of patients with non-small cell lung cancer imaged prior to surgical excision with both thin-section CT and whole body PET/CT scans acquired under IRB approval from Stanford University and the Veterans Administration Palo Alto Health Care System. Microarray data acquired from the excised samples corresponding to these scans is available on the NCBI Gene Expression Omnibus (http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE28827), where DICOM patient names correspond to microarray sample names. For scientific inquiries relating to the data-set please contact Drs. Sandy Napel (snapel@stanford.edu) or Sylvia K. Plevritis (sylvia.plevritis@stanford.edu). |
