Ultrasound Elastography is a new imaging technique that allows a noninvasive estimation and imaging of tissue elasticity distribution within biological tissues using conventional, Real Time Ultrasound equipment with modified software. It can be viewed as an electronic palpation of tissues. Introduced by Ophir et al in 1991, it subsequently evolved into a Real Time Imaging tool.
presentation on ultrasound elastography-introduction ,techniques,physics,application, interpretation and future prospects.sourced from multiple articles.
Physicians have used palpation to detect differences in tissue stiffness as an aid to diagnosis based on the fact that the mechanical properties of tissues are often dramatically affected by the presence of disease processes such as cancer, inflammation, and fibrosis. Elastography depends on the same differences in mechanical properties between healthy and abnormal tissues using imaging to detect these differences at depths not reachable by manual palpation and presents data in color-coded display, can be performed with ultrasound, using manual pressure or low frequency sonic waves, or by MR Elastography imaging.

This is the presentation of a clinical case of Multiple Myeloma with a thorough discussion on many aspects of the disease and on applications of Shear Wave Elastography.
Ultrasound gives today more informations both in morphology (through speed of sound optimisation and 3D acquisition) and in mechanical properties evaluations (it gives mean, maximum and minimum stiffness as well standard deviation in the ROI). Furthermore it's possible to draw freehand ROI, very useful to differentiate the tumor and the stiff surrounding stroma also in the C plane with 3D SWE. Here some clinical cases are presented.
In this presentation dr. Masciotra shows how the speed of sound selection in US imaging does change the informations of US data, both qualitative (morphology, echogenicity, spatial and contrast resolution) and quantitative (density of vessels, stiffness map) of the tissues examined.
In questa presentazione il dr. Masciotra analizza sulle immagini di casi clinici gli effetti della scelta della velocità del suono sulla qualità delle informazioni dei dati ecografici.
Come si può vedere il parametro della velocità del suono condiziona in maniera sensibile le informazioni sia qualitative (morfologia, ecostruttura, risoluzione spaziale e di contrasto) che quantitative (densità dei vasi e proprietà meccaniche come l'elasticità) dei tessuti esaminati.
Swe on breast cancer in dense breast with considerations on tnm stagingantonio pio masciotra
This case shows how dense breast can hinder cancer at mammography and the important role of US and SWE elastography in situation like this.
SWE could be the most reliable tool for the measurement of the 'T' parameter of TNM staging of breast cancer, especially if performed with 3D probe.

Ultrasound is currently the only mean to determine non-invasively:
•the elastic properties of the arterial wall material (Young's elastic modulus)
•the relationship between intima-media thickness (IMT) and elastic properties or the influence of inward or outward remodeling on arterial distensibility.
Here you find also a demonstration of UltraFast doppler technology in the study of the carotids and vertebral arteries.
UltraFast doppler acquisition lasts only a few seconds and then in postprocessing it is possible to do spectral analysis in up to 3 different vessels (or 3 different sites in the same vessel).
It automatically identifies the frames with :
1) Maximum velocities
2) Mean velocities
3) Peak sistolic velocity.
It's very fast and reliable.
Here is the presentation of a clinical case of breast cancer incidentally detected on a chest CT.
Topics on the roles and information of MRI,CT, mammography, ultrasound and shear wave elastography are discussed.
This is the slideshow of the presentation held at 3d International Meeting on Sono-Elastography in Pavia on Oct. 1st 2013 concerning both elastography of the testis and general considerations on elastography.
Queste sono le slides presentate al Terzo Meeting Internazionale di Sonoelastografia tenutosi a Pavia il 01/10/2013.
Vengono trattati sia l'elastografia del testicolo che gli aspetti più generali dell'elastografia con le sue prospettive di sviluppo.
