Duplicated images in MIMIC-CXR

[pdpino]

Hi, I read your paper Clinically Accurate Chest X-Ray Report Generation, and I have a question regarding duplicated images removed from the MIMIC-CXR dataset. The paper says "we eliminate duplicated radiograph images with adjusted brightness level or contrast as they are commonly produced for clinical needs". How do you know which images are duplicated from the dataset?. I'm using the dataset and I'd be interested to remove these duplicated images as well.

The paper also indicates you used an alpha version of the dataset. Do you know if the duplicated images still exist in the v2.0.0 of the dataset?

Thanks!
