Fig. 2From: Robust free-breathing SASHA T1 mapping with high-contrast image registration a Partial sequence diagram of the proposed high-contrast SASHA sequence showing a non-saturated image and a saturation recovery image. Image acquisition is extended by ~40Â ms by appending additional k-space lines (dashed red) to primary image readouts (light blue). b k-space coverage is shown for primary and high-contrast images. The lower half of k-space is shared between primary and high-contrast images and the additional k-space lines cover the central portion of k-spaceBack to article page
