To avoid errors in right ventricular T1 mapping caused by partial volume blood and epicardial fat signal we demonstrate a novel dark-blood fat-suppressed STEAM-SASHA method both in a phantom and in vivo.
Figure 4:Full field of view example STEAM-SASHA images after
averaging two sequence repeats (top line) with the associated STEAM-SASHA T1 map
(bottom left) and the equivalent systolic product MOLLI T1 map acquired in one
typical volunteer (T1 maps cropped). The
STEAM-SASHA images show the reduction in signal intensity at the top and bottom
of the image due to the in-plane slice select gradient used. The STEAM-SASHA T1
map provides excellent blood and fat suppression in the left and right
ventricles.
