From: Assessment of spinal cord injury using ultrasound elastography in a rabbit model in vivo
Association between USE and mechanical testing. (A) T1-weighted MR images alone (top) and compounded with axial normal strain elastogram (bottom, with spinal canal segmented) from a non-paralyzed rabbit (left) and a paralyzed rabbit (right). (B) Transverse plane engineering stress–strain curves of spinal cords extracted from the same rabbits as in (A). (C) Scatter plot of mean strain ratio measured by USE and mean Young’s modulus measured by mechanical testing (strain range 10%–20%). Dashed curve indicates a hyperbola fit.
