The purpose of this study was to compare the image quality of free-breathing CS-VIBE and TWIST-VIBE in patients with lung disease. In patients who were able to hold their breath well, the images quality of CS-VIBE and TWIST-VIBE were comparable (P>0.05). In patients who failed to hold their breath during the required period, CS-VIBE allowed for superior image quality, lesion delineation, artifact level, and diagnostic confidence compared to TWIST-VIBE. Our study demonstrated that free-breathing CS-VIBE is feasible for lung imaging for patients who have difficulties holding their breath.
