53,235 anonymized adult chest x-ray dataset in 1024 x 1024 pixel DICOM format with corresponding anonymized free-text reports from Dunedin Hospital, New Zealand between 2010 - 2020. Corresponding radiology reports generated by FRANZCR radiologists were manually annotated for 45 common radiological findings mapped to Unified Medical Language System (UMLS) and RadLex ontology. Each of the multiclassification annotations contains 4 types of labels, namely positive, uncertain, negative and not mentioned. In the provided dataset, image filenames contain patient index (enabling analysis requiring grouping of images by patients), as well as anonymized date of acquisition information where the temporal relationship between images is preserved. This dataset can be used for training and testing for deep learning algorithms for adult chest x rays.

To access the data, an ethics training process is required and is divided into 2 steps:

1. An online ethics course at https://globalhealthtrainingcentre.tghn.org/ethics-and-best-practices-sharing-individual-level-data-clinical-and-public-health-research/. You will need to register an account to be able to take the free online ethics course. Once you finished the course quiz, please send the course certificate to Sijing.Feng@southerndhb.govt.nz

2. Signing the Data Use Agreement. It can be accessed at Data_Use_Agreement_-_Hospital_Signed.pdf (trello-attachments.s3.amazonaws.com). Once you signed the Data Use Agreement, please also send the signed copy to Sijing.Feng@southerndhb.govt.nz

After successfully completion of both of above steps, a private link to download the dataset will be sent.
