We assessed a single pass gradient echo two-point Dixon sequence and a gradient echo sequence with spectral fat suppression in their performance at 3 Tesla for bilateral contrast-enhanced breast imaging. In eight patients evaluated by two breast imaging radiologists, improved fat suppression was achieved with the Dixon technique. Dixon technique was less sensitive to cardiac motion artifacts and improved the visualization of posterior structures. Margins and internal enhancement characteristics were better assessed in 28% of lesions. Our preliminary findings suggest that the Dixon technique may provide improved depiction of posterior structures and better anatomical definition of small lesions.
