Magnetic resonance elastography (MRE)is a medical imaging technique that images propagating mechanical waves using MRI. It non-invasively measures the stiffness of biological tissues. Pathological tissues are often harder than the surrounding normal tissue. This has also been utilized in ablative treatments done with Focused Ultrasound where the treated necrosed tissue can be distinguished with MRE even in real time.
Magnetic resonance elastography was first introduced by Muthupillai et al. in 1995.[1]
