People who have been exposed to high levels of second hand smoke have lasting damage to their lungs, MRIs show in a recent study of several non-smokers.
Researchers examined study participants using a special kind of MRI scan to evaluate changes in the lung tissue of secondhand non-smokers. Researchers used a special kind of magnetic resonance imaging (MRI) scans to review the lungs of non-smokers. The study revealed that one-third of nonsmokers exposed to extensive periods of smoking experienced structural changes in their lungs.
This study is significant because it was the first study of its kind to investigate secondhand smoking and the effects it has on other people. Scientists in this experiment were able to assay lung structure with MRIs to reveal epidemiological changes.
