What this trial studies

This observational study aims to determine the effectiveness of dual-energy CT scans in providing valuable information for patients undergoing bronchoscopic lung volume reduction for emphysema. Up to 30 adult participants will be enrolled at University Hospitals Cleveland Medical Center, where they will receive the valve placement procedure. The study focuses on assessing lung perfusion through advanced imaging techniques to enhance treatment outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with emphysema who are suitable for bronchoscopic lung volume reduction.

Not a fit: Patients who are unable to provide consent, pregnant or nursing women, and those with contraindications to dual-energy CT scans will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the precision of lung volume reduction procedures, leading to better patient outcomes.

How similar studies have performed: While this approach is innovative, similar studies using advanced imaging techniques have shown promise in enhancing procedural outcomes.
