Matched TCGA patient identifiers allow researchers to explore the TCGA\/TCIA databases for correlations between tissue genotype, radiological phenotype and patient outcomes. \u00a0Tissues for TCGA were collected from many sites all over the world in order to reach their accrual targets, usually around 500 specimens per cancer type. \u00a0For this reason the image data sets are also extremely heterogeneous in terms of scanner modalities, manufacturers and acquisition protocols. \u00a0In most cases the images were acquired as part of routine care and not as part of a controlled research study or clinical trial.\u00a0<\/p>
Imaging Source Site (ISS) Groups are being populated and governed by participants from institutions that have provided imaging data to the archive for a given cancer type. Modeled after TCGA analysis groups, ISS groups are given the opportunity to publish a marker paper for a given cancer type\u00a0per\u00a0the guidelines in the table above. This opportunity will generate increased participation in building these multi-institutional data sets as they become an open community resource. \u00a0Learn more about the\u00a0TCGA Head-Neck Phenotype Research Group<\/a>.<\/p> We would like to acknowledge the individuals and institutions that have provided data for this collection:<\/p>Acknowledgements<\/h3>
