ANOVA, analysis of variance; CAIPIRINHA-VIBE, controlled aliasing in parallel imaging results in higher acceleration with volumetric interpolated breath-hold examination; c-VIBE, conventional-VIBE; GOF, goodness-of-fit; KWIC-Radial-VIBE, radial-VIBE with k-space-weighted image contrast reconstruction; SD, standard deviation; SI, signal intensity; SNR, signal-to-noise ratio.
The numbers in parenthesis represent the 95% confidence interval.
