Synopsis

We combine advanced acquisition and reconstruction techniques for highly accelerated 3D brain imaging. A hybrid acquisition called META (Mixed Echo Train Acquisition) generates 3D T1W, T2W and FLAIR contrasts simultaneously and with high SNR efficiency. A 3D deep learning reconstruction (AIR Recon DL) reduces image noise, reduces artifacts, and enhances resolution relative to conventional reconstructions, solving the trade-off between SNR, scan time, and resolution. META with the DL Recon achieved 1mm isotropic T1W, T2W and FLAIR images within 4 minutes. These combinations are well suited in high resolution volumetric brain imaging.
