In this study a breathhold two-dimensional ultra-short TE (UTE) protocol was compared for imaging of the lung parenchyma and ventilation at 1.5T and 3T field strength. The resulting SNR values and parameter maps indicate a clear advantage for 3T. Proton fraction and SNR changes (anterior to posterior, expiration vs. inspiration) can be clearly assessed with both field-strength. Different resulting values for the lung and proton fractions need further attention.
