Comparison of post-contrast three-dimensional T1-weighted magnetization prepared rapid acquisition gradient recalled echo (MPRAGE) images acquired with conventional parallel imaging and wave-controlled aliasing in parallel imaging (CAIPI) encoding demonstrating a meningioma. Standard (a) and Wave-CAIPI (b) T1-weighted MPRAGE images show equivalent visualization of the dural-based enhancing mass along the parietal convexity. Both images were acquired on a 3-T Siemens Prisma MRI scanner equipped with 80 mT/m maximum gradient strength and 200 T/m/s maximum slew rate. The Wave-CAIPI sequence was more than twice as fast as the standard sequence (acquisition time = 2 min, 32 s for Wave-CAIPI compared to 5 min, 18 s for the standard sequence)
