      abstract     = {To introduce a highly accelerated T1-weighted
                      magnetization-prepared rapid gradient echo (MP-RAGE)
                      acquisition that uses wave-controlled aliasing in parallel
                      imaging (wave-CAIPI) encoding to retain high image
                      quality.Significant acceleration of the MP-RAGE sequence is
                      demonstrated using the wave-CAIPI technique. Here,
                      sinusoidal waveforms are used to spread aliasing in all
                      three directions to improve the g-factor. Combined with a
                      rapid (2 s) coil sensitivity acquisition and data-driven
                      trajectory calibration, we propose an online integrated
                      acquisition-reconstruction pipeline for highly efficient
                      MP-RAGE imaging.The 9-fold accelerated MP-RAGE acquisition
                      can be performed in 71 s, with a maximum and average
                      g-factor of gmax  = 1.27 and gavg  = 1.06 at 3T.
                      Compared with the state-of-the-art method controlled
                      aliasing in parallel imaging results in higher acceleration
                      (2D-CAIPIRINHA), this is a factor of 4.6/1.4 improvement in
                      gmax /gavg . In addition, we demonstrate a 57 s acquisition
                      at 7T with 12-fold acceleration. This acquisition has a
                      g-factor performance of gmax  = 1.15 and gavg
                       = 1.04.Wave encoding overcomes the g-factor noise
                      amplification penalty and allows for an order of magnitude
                      acceleration of MP-RAGE acquisitions. Magn Reson Med
