November 29, 2007 – A study presented at RSNA 2007, that used long-time-scale, global helium-3 diffusion magnetic resonance imaging (MRI), found that secondhand smoke damages lungs.
The study, conducted by researchers at the University of Virginia School of Medicine in Charlottesville and The Children's Hospital of Philadelphia, examined the lungs of 43 volunteers, including seven current and former smokers and 36 people who had never smoked, 18 of whom had a high level of exposure to secondhand smoke.
