Figure 7. — Single diastolic frames from a cardiac cine bSSFP acquisition performed at 3 T (a) and 1.5 T (b) acquired with the same imaging parameters, (TR/TE/Flip = 3.8 ms/1.9 ms/4 $5 °$ ), in the same subject. Due to the poorer field uniformity at 3 T compared to 1.5 T the characteristic bSSFP banding artifacts can be seen (arrows). Due to localised shimming over the heart the artifacts are displaced to the edges of the body. Note the improved SNR at 3 T. bSSFP, balanced steady state free precession; SNR, signal-to-noise ratio; TE, echo time; TR, repetition time.
