Autosegmentation of problematic Lung CT

During the preparation for the MONAILabel workshop, I noticed that in the public ML Task06_lung dataset there are several datasets with strange contrasts that display very “dark” initially.
Example: lung_049


These data are difficult for both manually assisted as well as AI segmentation. How do you guys handle these data? Could preprocessing help here?
