Pulmonary MR imaging using ultra-short echo times (UTE-MRI) was introduced as a new tool for quantitative measure of tissue integrity in the lung. We previously demonstrated that T2* and % change in signal intensity (SI) measured with this method correlate closely with lung tissue density and can detect ventilatory heterogeneity in the lung parenchyma. Here we report the use of UTE-MRI to assess pulmonary structural and functional abnormalities in a rat model of obesity-associated diabetes mellitus.
