Based on a 3D VIBE sequence with 3 flip angles and a
preceding B1 map, T1 maps of the whole liver were
acquired in 84 patients at 3 T before and after the
application of Gd-EOB-DTPA. B1 map as well as the T1
mapping sequence were measured during breath hold (14s,
17s). A single slice technique (2D TurboFLASH with 2
inversion times) was used additionally. 3D VIBE yielded
reliable results for T1 even in critical anatomical
regions like the left liver lobe. The reduction rate of
T1 relaxation times before and after Gd-EOB-DTPA
correlated well between both T1 mapping techniques.
