The brain of a 15-foot juvenile brain that washed ashore in the Bronx, New York City was scanned using a 7T whole-body MRI scanner. After fixation in PBS solution and vacuum removal of air pockets, the specimen was scanned using a battery of high-resolution anatomical MRI sequences, including T1-weighted MP2RAGE, 3D MERGE, Proton Density weighted imaging, T2-weighted FLAIR imaging and Diffusion Tensor Imaging. Post-processing included brain masking to alleviate bright background from the PBS solution in most imaging modalities. Anatomical imaging from three high resolution datasets is presented along with a 3D reconstruction generated by volumetric projection of data segmented using the FreeSurfer 6 algorithm.
