LUng voluMe reductIoN by DuAl ENergy CT Evaluation (LUMINANCE) Study

Recruiting

• Conditions: Lung Perfusion
• Interventions: Procedure: Dual Energy CT

• Registration Number: NCT05816239
• Lead Sponsor: Sameer Avasarala

Brief Summary

The purpose of this research study is to see if a special CT scan (dual-energy CT) provides useful information in patients undergoing bronchsoscopic lung volume reduction (valve placement for emphysema). The investigators will enroll up to 30 participants in this study from University Hospitals Cleveland Medical Center. All of the participants from this study will undergo their valve procedure at University Hospitals Cleveland Medical Center.
