CAIPIRINHA controlled aliasing in parallel imaging results in higher acceleration, DL deep learning, HR high resolution, MRI magnetic resonance imaging, VIBE volumetric interpolated breath-hold examination

For precontrast image, standard CAIPIRINHA-VIBE and DL CAIPIRINHA-VIBE were performed

For HBP image, standard CAIPIRINHA-VIBE, DL CAIPIRINHA-VIBE, and HR-DL CAIPIRINHA-VIBE were performed
