CAIPIRINHA-VIBE, controlled aliasing in parallel imaging results in higher acceleration with volumetric interpolated breath-hold examination; c-VIBE, conventional-VIBE; KWIC-Radial-VIBE, radial-VIBE with k-space-weighted image contrast reconstruction; RMANOVA, repeated measures analysis of variance.
The numbers in parenthesis represent the 95% confidence interval of the average score of image quality.
