Early COPD diagnosis possible with nuclear medicine
Date:4/1/2013

Reston, Va. (April 1, 2013) In vivo ventilation/perfusion (V/Q) imaging can detect early changes to the lung caused by cigarette smoke exposure and provides a noninvasive method for studying lung dysfunction in preclinical models, according to research published in the April issue of The Journal of Nuclear Medicine. These measures have the potential to be applied clinically to study and diagnose the early stages of chronic obstructive pulmonary disease (COPD).

COPD is a slow-progressing, debilitating lung disease which is commonly caused by cigarette smoking. Defining characteristics of COPD include chronic inflammation, increased mucus production, small-airway fibrosis and airspace enlargement. Many people with COPD, however, go undiagnosed until their disease has reached a more symptomatic stage and irreversible damage has occurred.

"Better diagnostic tools are needed to detect early changes in smokers to prevent further lung dysfunction and provide patients with individualized treatment regimens," said N. Renee Labiris, PhD, one of the authors of the study "Detection of Lung Dysfunction Using Ventilation and Perfusion SPECT in a Mouse Model of Chronic Cigarette Smoke Exposure." "Our preclinical study suggests that not only can V/Q imaging detect early and small changes in lung pathology, the type of V/Q mismatching could provide insight into the underlying pathologies, which current measures of lung function are unable to do."

In the study, groups of mice were exposed to cigarette smoke for 50 minutes twice daily, five days a week, for either eight or 24 weeks. Age-matched control groups of mice were also included in the study for comparison. After the final cigarette smoke exposure, V/Q single photon emission computed tomography (SPECT) was performed, followed by a computed tomography (CT) scan. Histologic lung sections were then collected and a semiautomated quantitative analysis of airspace enlargement was applied to wh
