简要总结
The aim of study is to differentiate between testicular tumors by their elastographic criteria (Stiffness [hard to soft] , Shape under compression , etc.) using ultrasound elastography techniques (shear wave/strain elastography) on suspected testicle that showed specific lesion on normal ultrasound examination.
详细描述
Technique:
Using a linear ultrasound probe supporting elastography techniques, either :
Strain Elastography (SE) SE measures tissue stiffness by applying external tissue pressure [3]. Tissue dimensions change due to the applied pressure; this deformation is termed strain. Stiffer lesions deform less, and have correspondingly lower strain and higher Young's modulus.
In strain imaging, tissue displacement is calculated by processing radiofrequency (RF) datasets obtained before and after compression [4]. Translucent colored elastograms (strain images) can be superimposed on B-mode images to provide complementary anatomic information. It is common to display the strain map as colored pixels on a red/blue scale or gray scale [5].
Or Shear wave elastography (SWE) Shear wave elastography differs from strain elastography, as it is a quantitative method of assessing tissue elasticity by measuring the speed of acoustic radiation force impulse-induced shear waves traveling in the tissue of interest.
