Novel Acoustic Radiation Force Impulse Imaging Methods for Visualization of Rapidly Moving Tissue

Acoustic Radiation Force Impulse Imaging for Differentiation of Thyroid Nodules

BACKGROUND Acoustic Radiation Force Impulse (ARFI)-Imaging is an ultrasound-based elastography method enabling quantitative measurement of tissue stiffness. The aim of the present study was to evaluate sensitivity and specificity of ARFI-imaging for differentiation of thyroid nodules and to compare it to the well evaluated qualitative real-time elastography (RTE). METHODS ARFI-imaging involve...

Acoustic radiation force impulse imaging of kidneys – a phantom study

AIM OF THE STUDY Since there have been only few works reporting the diagnosis of kidneys using Acoustic Radiation Force Impulse technique and those works do not provide consistent results of shear wave velocity measurements in renal tissue, we have decided to use kidney phantoms with known properties to examine the reliability of the method itself in a controlled setup similar to kidneys examin...

Acoustic radiation force-based elasticity imaging methods.

Conventional diagnostic ultrasound images portray differences in the acoustic properties of soft tissues, whereas ultrasound-based elasticity images portray differences in the elastic properties of soft tissues (i.e. stiffness, viscosity). The benefit of elasticity imaging lies in the fact that many soft tissues can share similar ultrasonic echogenicities, but may have different mechanical prop...
