Magnitude images, filtered shear wave, and stiffness estimations of a mouse brain at different time points: before injury, immediately, and 24 h, 7 days, and 28 days following controlled cortical impact (CCI) injury with a 0.75 mm indentation depth. The injury site was located on one hemisphere, highlighted on the magnitude images. This reduction pattern can also be noticed by shorter wavelength in the shear wave images in the injured regions.
