Magnetic resonance imaging of the lung is challenging due to low proton density, short T2*, respiratory and cardiac motion. Single-shot turbo spin-echo (ssTSE) sequences can be used to obtain good signal-to-noise ratio in the lungs and to suppress motion artifacts. However preparation schemes such as diffusion and T2* preparation can result in the violation of the CPMG conditions and generate severe artifacts. In this work we present the application of a non-CPMG ssTSE sequence to diffusion-weighted and T2*-weighted imaging of the human lung. We show that this approach allows for apparent diffusion coefficient (ADC) and T2* mapping of the human lung in a single 10s breath-hold.
