Frame Rate Considerations for Real-Time Abdominal Acoustic Radiation Force Impulse Imaging

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...

Magnetic resonance acoustic radiation force (impulse) imaging (MR-ARFI)

Background/introduction MR-ARFI adds to the rich toolbox of MR imaging methods for guiding focused ultrasound. MRI has exquisite soft tissue contrast for targeting focused ultrasound and a variety of contrast mechanisms for assessing the effect of focused ultrasound. In addition, MR can provide temperature mapping in near-realtime. MR-ARFI is an imaging method that compliments these other capab...

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...
