About Term Definition and Consistency

[wizardlancet]

Thanks for your great works. I have a few questions and need your generous help.

As mentioned in Structured dataset documentation: a datasheet for CheXpert, the terms are from ”Fleischner Society: Glossary of Terms for Thoracic Imaging,“. However I can not find the definition of some labels like Lung Lesion. This seems to be a vague label with many situations.

Also in the peper's figure 1, Cadiomegaly seems to be a special situation of Enlarged Cardiomediastinum, while there are not all the Cadiomegaly positive cases with positive labels on Enlarged Cardiomediastinum.

Is there any detailed information for term definition an if there are some self consistency in the labeling procedure?
