Figure 9
Representative balanced steady-state free-precession images of the left ventricle. The 4-chamber (A) and short-axis (B) views from subjects with various body types, shown in increasing order of BSA (Left to Right) is shown. Without (W/o) radiofrequency (RF) shimming, B1 field inhomogeneity is observed (top row) in both A and B; this inhomogeneity is reduced with RF shimming (bottom row). BMI, body mass index; BSA, body surface area; AP/RL, anterior-posterior/right-left ratio.
