elastogram

elastogram

An image of tissue strain obtained by elastography, which reflects the degree of adherence of a tumour to the surrounding soft tissue.

In qualitative ARFI, short acoustic pulses and high intensities are used to deform the elements of the tissue and create a static map (elastogram) of the relative stiffness of the tissue.
It consists of qualitative virtual touch tissue imaging, displaying a color-coded elastogram of comparative tissue stiffness and quantitative virtual touch tissue quantification (VTQ).
The profile of tissue deformation is converted to an elastic modulus from which an image called an elastogram is derived.
The distortion of tissues can be observed by ultrasonographic imaging, and areas of decreased strain can be recorded, creating a map of elasticity, known as an elastogram (figures 3 and 4).
The frequency was adjusted from 2 Hz to 4 Hz depending on each individual and condition so that the elastogram was sufficiently superimposed on the ROI.
(b) A single wave image from MRE performed at 100 Hz is shown along with (c) the corresponding elastogram. (d) An overlay image of the elastogram and the magnitude image shows good correlation between the tumor and the stiff region detected by MRE (adapted from [15]).
Ultrasonography elastogram was displayed over the B-mode image in a colour scale comprising, red for nodes with greatest elastic strain (soft), green for intermediate and blue for nodes with no strain (hardest) as shown in Figure 2.
The elastography grading score can be affected by subjective factors because it is usually recorded according to the elastogram color distribution characteristics.
The elastogram was exhibited over the B-mode image in a colour scale: red (greatest strain, softest component) and blue (no strain, hardest component) tissue.
Our results show that Young's modulus values are in the range of 103 kPa to 137 kPa compared with the values given in [27] (30 kPa to 100 kPa), where Young's modulus is obtained from pressure column and from elastogram at low temperatures.
Of the 140 biopsies, the elastogram image correlated with the standard B-mode ultrasound image in 58 of the 59 cancers (98%), said Dr.
