Study: Total Airway Count Can Be Used to Measure Pulmonary Decline in COPD

The research suggests a computed tomography-readable biomarker could help clinicians better understand individual cases of chronic obstructive pulmonary disease. Total airway count (TAC) as visible in computed tomography (CT) scans appears to be associated with chronic obstructive pulmonary disease (COPD) severity and could be a meaningful predictor of pulmonary decline in such patients, according to new research. Writing in the International Journal of Chronic Obstructive Pulmonary Disease, corresponding author Pixin Ran, of the First Affiliated Hospital of China’s Guangzhou Medical University, and colleagues said the use of micro-CT has demonstrated that patients with COPD have significant damage to their peripheral bronchioles and small conducting airway. Yet, the investigators said, those measurements can be burdensome, since in vitro lung tissue is required to perform the micro-CT. At the same time, Ran …
