Mean and standard deviation of Young’s modulus of the plaques and vessel walls. These values were estimated from the recovered elastograms recovered with the three imaging approaches. We also report the values from independent mechanical testing of representative samples.

Phantom #1: plaque	$8.5\pm 1.5$	$6.1\pm 1.8$	$8.1\pm 1.3$	$7.4\pm 1.3$
Phantom #1: vessel wall	$31.4\pm 3.5$	$29.2\pm 3.9$	$34.1\pm 3.4$	$30.7\pm 2.1$
Phantom #2: plaque	$7.5\pm 0.3$	$4.2\pm 0.9$	$10.7\pm 0.4$	$7.2\pm 0.1$
Phantom #2: vessel wall	$28.0\pm 2.5$	$21.7\pm 8.1$	$26.0\pm 8.6$	$32.1\pm 8.4$
