Nothing is seen with the B-mode image…
Hard tissues are clearly seen with Elastography.
It is captured objectively that the low echo area in a mammary gland has the same hardness as that of a surrounding normal mammary gland.
It is apparently harder than surrounding tissues and fringed in red since distortion is seriously generated in the boundary.
Difference of hardness from that of a normal mammary gland is observed even in the non invasive early cancer.
Not only a low echo area but also the boundary of tumor including the hollow area is observed in the E-mode.
Elastic coefficient: The unit of hardness. Harder as a value is larger.
(T.A.Krouskop et al,Ultrasonic Imaging,1998)
With a simple operation only by putting the probe same as that used for normal examinations on the body surface and applying slight compression, elastic image can be obtained in real time.
An attachment is prepared to make easy to apply uniform compression by widening the contact area with the body surface.
Any probe is ready for Real-time Tissue Elastography. Also, EUP-L53L provides ultra wide filed-of-view over 90mm.
