VinDr-CXR: An open dataset of chest X-rays with radiologist annotations

We describe here a dataset of more than 100,000 chest X-ray scans that were
retrospectively collected from two major hospitals in Vietnam. Out of this raw
data, we release 18,000 images that were manually annotated by a total of 17
experienced radiologists with 22 local labels of rectangles surrounding
abnormalities and 6 global labels of suspected diseases. The released dataset
is divided into a training set of 15,000 and a test set of 3,000. Each scan in
the training set was independently labeled by 3 radiologists, while each scan
in the test set was labeled by the consensus of 5 radiologists. All images are
in DICOM format and the labels from training and test sets are made publicly
available.
