A 23-year-old male asked:

is there any way to do a lung angiogram without contrast dyes?

Possibly : Sometimes carbon dioxide can be used for angiograms to limit the use of contest dye. You would need to talk to a radiologist to see if this is offered in your area.

Lung vasculature: Unfortunately in order to visualize the blood vessels there needs to be some type of contrast agent used. Some of the newer agents are better tolerated than the older ones, but doing a lung angiogram is an invasive procedure and should only be done when necessary.
