This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers are studying whether lung ultrasound—a simple, radiation-free imaging technique—can accurately detect emphysema, a type of lung damage seen in chronic obstructive pulmonary disease. Currently, doctors use CT scans to find emphysema, but CT involves radiation exposure and isn't always available. This study will compare ultrasound images with CT scans to see if ultrasound could become a safer, easier alternative for detecting this condition.
CT scans can clearly show emphysema but expose patients to radiation and are not always accessible in routine clinical care. Researchers hope that lung ultrasound could offer a safer, more available way to detect and monitor emphysema in patients with chronic obstructive pulmonary disease.

You likely don't qualify if…
If you qualify, you will have lung ultrasound imaging performed using both standard clinical machines and a research platform, as well as a chest CT scan. Your ultrasound findings will be compared with your CT results to help researchers understand how well ultrasound can detect emphysema. Some participants will also complete a special breathing test called respiratory oscillometry. The study involves imaging and testing only—no medications or invasive procedures.
