New research could revolutionize how we treat chronic lung disease
Submitted by Communications & Public Affairs, Providence Health Care
Scientists have discovered a new way to identify people at risk of chronic obstructive pulmonary disease (COPD). This significant finding could lead to earlier detection of the progressive lung disease and ultimately transform how patients are treated.
In a recent study published in the American Journal of Respiratory and Critical Care Medicine, researchers from the Centre for Heart Lung Innovation (HLI) at St. Paul’s Hospital, in collaboration with clinicians at the University of Michigan and Temple University, discovered a novel non-invasive imaging biological marker, or “biomarker,” that detects damage to the small airways.
Principal author Dr. Dragoş Vasilescu, a research associate at the HLI, analyzed lung samples from COPD patients who had received a lung transplant and validated that a clinically available CT imaging biomarker can detect small airways disease. To do this, Dr. Vasilescu used his expertise in ultra-high-resolution micro CT imaging, and one of three specialized micro CT scanners available in Canada at the HLI, and funded by the St. Paul’s Foundation.
