(a) Free-breathing abdominal scan of an 80-year-old patient with gallstones and liver carcinoma. Results are shown for Dixon-RAVE (left-hand side), respiratory-resolved XD-Dixon-RAVE (center column, inspiration phase), and conventional Cartesian breath-hold Dixon (right-hand side).
Due to breathing motion, gallstones are slightly blurred with Dixon-RAVE. This is resolved with both XD-Dixon-RAVE and breath-hold acquisition. In partition 2, the liver carcinoma (solid arrows) is clearly depicted. Due to residual motion in the breath-hold exam, ghosting artifacts occur in the Cartesian Dixon scan (dashed arrow), which is not the case for the radial acquisitions.
