Fig. 4A —Subjective image quality of all four techniques: navigator-guided
(NAV) coronary MR angiography, k-space weighted motion-adapted gating (k-MAG),
and sensitivity encoding (SENSE, factor = 2). Image quality of all four
techniques is greater than 2.5, indicating that the overall image quality was
between good and very good (see text for description of scale). Mean image
scores of techniques without SENSE were rated slightly above 3.0, and mean
scores of techniques using SENSE were rated slightly above 2.5.
