New test could identify smokers at risk of emphysema
Date:4/6/2010

Using CT scans to measure blood flow in the lungs of people who smoke may offer a way to identify which smokers are most at risk of emphysema before the disease damages and eventually destroys areas of the lungs, according to a University of Iowa study.

The study found that smokers who have very subtle signs of emphysema, but still have normal lung function, have very different blood flow patterns in their lungs compared to non-smokers and smokers without signs of emphysema.

This difference could be used to identify smokers at increased risk of emphysema and allow for early intervention. The findings appear this week in the Early Edition of the Proceedings of the National Academy of Sciences.

"We have developed a new tool to detect early emphysema-related changes that occur in smokers who are susceptible to the disease," said lead study author Eric Hoffman, Ph.D., UI professor of radiology, internal medicine and biomedical engineering. "Our discovery may also help researchers understand the underlying causes of this disease and help distinguish this type of emphysema from other forms of chronic obstructive pulmonary disease. This type of CT scan could even be a tool to test the effectiveness of new therapies by looking at the changes in lung blood flow."

As many as 24 million Americans have chronic obstructive pulmonary disease (COPD) -- a group of serious lung diseases that includes emphysema -- and COPD is the fourth leading cause of death nationwide. Because COPD is a group of different diseases, identifying more effective treatments may hinge on distinguishing between these diseases and targeting them separately.

The team used multi-detector row CT imaging to measure blood flow patterns in the lungs of 41 study participants -- 17 non-smokers and 24 smokers. All the participants had normal lung function, but 12 of the smokers had very subtle signs of emphysema. The CT scans showed that these 12 individual
