The AIMI Initiative: AI-Generated Annotations for Imaging Data Commons Collections
The Image Data Commons (IDC) contains publicly available cancer radiology datasets that could be pertinent to the research and development of advanced imaging tools and algorithms. However, the full extent of its research capabilities is limited by the fact that these datasets have few if any, annotations associated with them. Through this study with the Artificial Intelligence (AI) AI in Medical Imaging (AIMI) initiative, we produced high-quality, AI-generated imaging annotations of tissues, organs, and/or cancers for 11 distinct medical imaging collections from the IDC. These collections have a variety of image modalities, computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET) imaging modalities. Furthermore, the imaging collections cover various body parities, such as the chest, breast, kidneys, prostate, and liver. Both publicly available and novel AI algorithms were adopted and further developed using open-sourced data coupled with expert annotations to create the AI-generated annotations. A portion of the AI annotations were reviewed and corrected by a radiologist to assess the AI model's performance. Both the AI's and the radiologist's annotations conformed to DICOM standards for seamless integration into the IDC collections as third-party analyses. All the models and datasets (images and annotations) are publicly accessible.
