While not visible on conventional grayscale ultrasound (left), a strain elastography image (centre) of the prostate gland detects a cancer (dark red area at lower left). The finding is confirmed by histology. Elastography is used for the investigation of many disease conditions in many organs.
The first OCT elastography of arteries was done by the Brezinski group in 2004 [9] But the term optical coherence elastography was first coined in a 2004 paper with Brett Bouma. [10] Requiring no injections, OCE is a non-invasive imaging method can gives more details than ultrasound or MRI.
Tomoelastography of the abdomen; upper a healthy state, lower with malignancy.. Tomoelastography (from ancient Greek τόμος tomos, “slice” and elastography – imaging of viscoelastic properties) is a medical imaging technique that provides quantitative maps of the mechanical properties of biological soft tissues with high spatial resolution (called elastograms).
The wide clinical use of ultrasound elastography is a result of the implementation of technology in clinical ultrasound machines. Main branches of ultrasound elastography include Quasistatic Elastography/Strain Imaging, Shear Wave Elasticity Imaging (SWEI), Acoustic Radiation Force Impulse imaging (ARFI), Supersonic Shear Imaging (SSI), and ...
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Magnetic resonance elastography (MRE) is a form of elastography that specifically leverages MRI to quantify and subsequently map the mechanical properties (elasticity or stiffness) of soft tissue. First developed and described at Mayo Clinic by Muthupillai et al. in 1995, MRE has emerged as a powerful, non-invasive diagnostic tool, namely as an ...

This project is based on MRI elastography, which is the reference method for in vivo, in situ and non-perturbative measurement of the strain, that is to say the very small elastic strain caused in the tissue will give access to the measure of "stress" that is to say of the constraint.
