PR rFOV image with 48 Np (as compared to Cartesian rFOV with 48 phase-encodings) and matched scan parameters. Scan parameters: SSFP, TR = 4.1 ms, flip angle = 60°, receiver bandwidth = ±62.5 kHz, slice thickness = 8 mm slice. PR: FOV = 32 cm, 160 × 48 Np, Cart: FOV = 34 × 34 cm, 192 × 48 Ny. a: Representative Cartesian frames with least aliasing and most aliasing reconstructed with the LL80% and LL95% filters. b: Representative PR frames with least aliasing and most aliasing reconstructed with the LL80% and LL95% filters. Greater aliasing results from the use of the filter with a greater temporal frequency passband, as expected. The aliasing (shown by arrows) presented here was due to breathing or catheter motions, and appeared in synchrony with the respiratory cycle. In frames in which aliasing was greatest, the aliasing with PR was less obstructive.
