Radiology Rounds – 5/3/22

Posted on by

This week on #RadiologyRounds we continue our series on COPD. Make sure to listen to all our episodes made in collaboration with the ATS Clinical Problems Assembly.

The CT shows moderate to severe centrilobular emphysema. These different patterns of emphysematous changes on CT can be related to the underlying driver of the disease and to symptom and disease severity.

In terms of follow-up, would you test this patient for alpha 1 anti-trypsin deficiency?

Current GOLD guidelines recommend that everyone with COPD, regardless of age or ethnicity should be tested for alpha 1 anti-trypsin deficiency.
