In this study MR imaging was used to study the effects of tobacco smoke on lungs. Experiments were performed on both human smokers and mice exposed to tobacco smoke. T1 changes in the lungs were found in both human smokers and tobacco smoke exposed mice. A translational link between humans and animals exposed to tobacco smoke expressed as decreased T1 has been demonstrated. Using MRI tobacco exposed animals may be a translational animal model of COPD.
