Clinical MR lung imaging is being increasingly done to avoid ionizing radiation especially in longitudinal studies. In this work, we optimize a 3D stack of stars acquisition to perform high SNR complete lung imaging in a single breath-hold. Ten consecutive volunteers were scanned on a 3T scanner for axial and coronal breath-hold images. The images were analyzed for SNR in lung parenchyma. Results indicate the suitability of the technique for robust lung imaging in a clinical setting.
