The aggregation of an imaging data set is a critical step in building artificial intelligence (AI) for radiology. Imaging data sets are used in various ways including training and/or testing algorithms. Many data sets for building convolutional neural networks for image identification involve at least thousands of images but smaller data sets are useful for texture analysis, transfer learning, and other programs.
Many commercial AI products are built on proprietary data sets or specific hospital data sets not available due to concerns over patient privacy. There are however several imaging data sets of radiological images and/or reports publicly available at the following websites:
- 1000 Functional Connectomes Project: over 1000 functional MRI exams collected from sites across the globe
- ACR Data Science: list of ~20 data sets
- CANDID-PTX dataset1: 19,237 chest X-ray Dicom images with segmentation labels for pneumothorax, rib fractures, and chest tubes and corresponding free text reports from New Zealand.
