Acoustic Radiation Force Impulse (ARFI) of the pancreas

Evaluation of ultrasound based acoustic radiation force impulse (ARFI) and eSie touch sonoelastography for diagnosis of inflammatory pancreatic diseases.

CONTEXT Pathology changes the consistency of the tissues. OBJECTIVE To prospectively assess the accuracy of per-abdominal US elastography in the form of acoustic radiation force impulse--virtual touch tissue quantification (ARFI-VTQ) and eSie touch elasticity imaging in characterizing and differentiating inflammatory pancreatic diseases. PATIENTS One-hundred and 66 patients from among the p...

Evaluation of spleen stiffness with acoustic radiation force impulse (ARFI): a comparison with histology in the assessment of liver fibrosis

Evaluation of Acoustic Radiation Force Impulse Imaging (ARFI) for the Determination of Liver Stiffness Using Transient Elastography as a Reference in Children.

PURPOSE Transient elastography (Fibroscan(©); (FS)) and acoustic radiation force impulse imaging (ARFI) represent noninvasive, user-friendly and quick methods providing an objective and reproducible measure of liver stiffness. The aim of the study was to evaluate cut-off values and performance of ARFI measurements in children using transient elastography as a reference. METHODS/PATIENTS A tot...

Session: 2C

Acoustic Radiation Force Impulse (ARFI) imaging uses brief, high-intensity, focused ultrasound pulses to generate radiation force in tissue. The absorption of acoustic energy also generates tissue heating. The purpose of this work is to study the maximum acoustic intensities that can safely be used in ARFI imaging, and to characterize the effects of tissue heating on ARFI displacement tracking....

Acoustic radiation force impulse imaging with Virtual Touch™ tissue quantification: mean shear wave velocity of malignant and benign breast masses

Acoustic radiation force impulse imaging (ARFI) with Virtual Touch™ tissue quantification (VTTQ) enables the determination of shear wave velocity (SWV) in meters per second (m/s). The aim of our study was to describe the mean SWV in normal breast tissue and various breast masses. We performed measurements of SWV with ARFI VTTQ in 145 breast masses (57 malignant, 88 benign) and in the adjacent b...
