IDC September 2022 release - clinical data

NCI Imaging Data Commons September 2022 release is out!


Along with the addition to 9 new collections, the main highlight for this release is the availability of clinical data collections, which until now have only been available in spreadhseets that followed collection-specific organization. With this release we ingested clinical data for most of the collections into BigQuery tables, so that you can search both the names of the columns available in the source spreadsheets and the values assigned to those columns. Each clinical data table contains the patient identifier matching DICOM PatientID to simplify linking with imaging data. The recommended way to get started with understanding clinical data in IDC is this new notebook.


This month we conducted IDC tutorial at the annual meeting of the NCI Informatics Technology for Cancer Research (ITCR). You can see the agenda and pointers to the notebooks used in the tutorial here. The newly released “getting started” notebook will hopefully serve as a gentle introduction into the organization of data in IDC and its main features.
