Factors Associated with the Quality of Transient Elastography
Digestive Diseases and Sciences, 2015Transient elastography is a noninvasive method for the evaluation of fibrosis in chronic liver disease. However, its reliability is variable, and the factors associated with its accuracy have not been identified completely.To identify the factors associated with the reliability of transient elastography.A total of 2033 transient elastography ...

Transient elastography in biological tissues
The Journal of the Acoustical Society of America, 1999Elastography is used in different ways to characterize soft tissues. Ophir uses static elastography to estimate strains in the tissue after a quasi-static compression. Strains can also be measured by sonoelasticity using mechanically forced low-frequency vibrations and the ultrasonic pulsed Doppler method (Parker and Sato).

Transient Optical Coherence Elastography
2021Transient optical coherence elastography (OCE) has undergone rapid development over the past couple of decades with introductions of new techniques for inducing motion in tissues, developments of robust signal processing algorithms, and demonstrations of transient OCE methods in humans in vivo.

The important result presented in this paper is the possibility of imaging the propagation of a transient low frequency shear wave in biological tissues by means of an ultra-fast ultrasonic imaging system which is described in this paper. This imaging system can produce up to 10,000 frames per second in the medium.

To compare point shear wave elastography (pSWE, ElastPQ®) and transient elastography (TE) with Liver Biopsy in order to evaluate fibrosis stage in non-alcoholic fatty liver disease (NAFLD).Our prospective study from September 2017 to October 2020 included 50 consecutively enrolled patients with NAFLD (52.2 ± 13.0 years, 32 male). All patients underwent

New developments in transient elastography
The Journal of the Acoustical Society of America, 2006An ultra-high-rate ultrasonic scanner has been developed that can give 5000 ultrasonic images per second of the body. With such a high frame rate, the propagation of transient shear waves can be followed, and from the spatio-temporal evolution of the displacement fields, various inversion algorithms allow us to recover the shear modulus map.

Transient elastography in heterogeneous tissues
The Journal of the Acoustical Society of America, 2008The Fibroscan® (Echosens, Paris, France) is a transient elastography based device used to quantify liver fibrosis by following the propagation of a low frequency shear wave and measuring the mean Young's modulus of the liver. This device has been successfully applied to homogeneous tissues such as liver in patients with chronic hepatitis C.

Study of anisotropy by transient elastography
The Journal of the Acoustical Society of America, 2002From the low-frequency (150 Hz) shear-waves’ velocity, transient elastography can precisely measure the Youngs modulus in isotropic soft tissues. Using polarized shear waves, the character of an anisotropic media like fiber muscle is clearly visible. The polarization of elastic shear waves is obtained by the use of a rod (3×80 mm) as a low-frequency ...

Improving arrival time identification in transient elastography
Physics in Medicine and Biology, 2012In this paper, we improve the first step in the arrival time algorithm used for shear wave speed recovery in transient elastography. In transient elastography, a shear wave is initiated at the boundary and the interior displacement of the propagating shear wave is imaged with an ultrasound ultra-fast imaging system.
