Study: E-cigarette Aerosol Enhances Optical Imaging of Lung Tissue
Russian researchers from Saratov and Tomsk universities have found that e-cigarette aerosols can enhance lung tissue contrast, potentially improving accuracy in diagnosing lung diseases.

According to a report from ABnews, research teams from two state universities in Saratov and Tomsk, Russia have recently published a study in the journal Diagnostics. The study suggests that aerosols in e-cigarettes can enhance the optical imaging contrast in lung tissue, offering the potential to improve the accuracy of diagnosing lung diseases.


This experiment simulated the use of e-cigarettes and was conducted on rats. It found that the morphology of lung tissue formation is altered by the inhalation of e-cigarette aerosol, affecting its gas exchange capabilities.
