Combined Endorectal Ultrasonography and Strain Elastography for the Staging of Early Rectal Cancer [PDF]
Colorectal Disease, 2015 Aim: Strain elastography is a novel approach to rectal tumour evaluation. The primary aim of this study was to correlate elastography to pT stages of rectal tumours and to assess the ability of the method to differentiate rectal adenomas (pT0) from early

A Least-Squares Strain Estimator for Elastography
Ultrasonic Imaging, 1997A least-squares strain estimator (LSQSE) for elastography is proposed. It is shown that with such an estimator, the signal-to-noise ratio in an elastogram ( SNR e ) is significantly improved. This improvement is illustrated theoretically using a modified strain filter and experimentally using

Semiquantitative Strain Elastography of Liver Masses
Journal of Ultrasound in Medicine, 2012This study was designed to determine the utility of semiquantitative strain elastography in differential diagnosis of solid liver masses.A total of 103 patients with focal liver masses underwent abdominal sonographic examinations and freehand elastography of focal hepatic lesions.

An adaptive strain estimator for elastography
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1998Elastography is based on the estimation of strain due to applied tissue compression. In conventional elastography, strain is computed from the gradient of the displacement estimates between gated pre- and postcompression echo signals. Gradient-based estimation methods are known to be susceptible to noise.

2002 IEEE Ultrasonics Symposium, 2002. Proceedings., 2003
In the breast, prostate and other organs increased tissue stiffness is often associated with the presence of disease. While palpation remains widely used, it has limited sensitivity which is highly dependent upon the skill of the clinician. To overcome this and other limitations a variety of automated approaches have been developed in recent years ...

Power spectral strain estimators in elastography
Ultrasound in Medicine & Biology, 1999Elastography can produce quality strain images in vitro and in vivo. Standard elastography uses a coherent cross-correlation technique to estimate tissue displacement and tissue strain using a subsequent gradient operator. Although coherent estimation methods generally have the advantage of being highly accurate and precise, even relatively small ...

Strain elastography for the assessment of skin nodules in dogs
Veterinary Dermatology, 2021BackgroundStrain elastography (SE) is a modern imaging technology that provides an additional way of evaluating the changes in soft tissue elasticity caused by pathophysiological processes. Despite its widespread use in human medicine, only a few studies on the application of SE in veterinary medicine are available.ObjectivesTo evaluate the potential ...

Limits on the contrast of strain concentrations in elastography
Ultrasound in Medicine & Biology, 1998Using an analytic solution of the elasticity equation derived for a cylindrical inclusion, it is shown that the contrast of the strain concentrations is limited for both hard and soft lesions. This means that, beyond a given elastic modulus contrast, the strain concentrations remain virtually constant.
