Chemical shift encoding-based
water-fat imaging, or Dixon imaging, has recently been demonstrated to permit first-pass
peripheral MRA without subtraction. While previous work focused on an
evaluation at 1.5 T, this work explores the feasibility of this subtractionless method at 3 T. Results on the first six patients are presented and are compared with the
established subtraction method. Substantial improvements in image quality are seen,
and the use of three stations is, despite particular challenges at 3 T, preliminarily
found to be practicable.
