Using 3D dual echo UTE sequence, all cholesterol gallstones were able to be detected as positive signal in-vitro. Our study may indicate that UTE has an added value of depicting impacted stones or hepatolithiasis as positive signal. In initial clinical experiences, cholesterol gallstones were also successfully visualized as positive signal with UTE.
