Technical Parameters of Different MR Sequences Used in Study
Sequence | T1-weighted VIBE Dixon | T1-weighted TSE coronal |
TR/TE (ms) | 3.60/1.23–2.46* | 600/8.7 |
Slice thickness (mm) | 3.12 | 5 |
Gap (%) | 0 | 30 |
Matrix | 192 × 121 | 384 × 230 |
Field of view (mm) | 500 | 450 |
% phase field of view | 100 | 67.2 |
Acquisition time (min:s) | 0:19 | 1:11 |
Number of excitations | 1 | 1 |
iPAT factor | 2 | 2 |
↵* Fat-saturation techniques with Dixon require 2 repetition times.
TR/TE = repetition time/echo time; iPAT = integrated parallel acquisition technique.
