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...
متن کاملAchilles tendon elasticity decreases with intermittent claudication in patients by Acoustic Radiation Force Impulse Imaging (ARFI).
OBJECTIVE To investigate the value of Acoustic Radiation Force Impulse elastography and its application in Achilles tendon elasticity of intermittent claudication due to lower extremity arterial ischaemia. METHODS This prospective case-control study was conducted at the Department of Radiology, Faculty of Medicine, Baskent University, Istanbul, Turkey, from October 2015 to January 2016, and c...
متن کاملMeasuring molecular elasticity by atomic force microscope cantilever fluctuations.
In single-molecule mechanics experiments the molecular elasticity is usually measured from the deformation in response to a controlled applied force, e.g., via an atomic force microscope cantilever. We have tested the validity of an alternative method based on a recently developed theory. The concept is to measure the change in thermal fluctuations of the cantilever tip with and without its cou...
متن کاملPreclinical evaluation of acoustic radiation force impulse measurements in regions of heterogeneous elasticity
PURPOSE The purpose of this study was to compare the reliability of ultrasound-based shear wave elastography in regions of homogeneous versus heterogeneous elasticity by using two different probes. METHODS Using acoustic radiation force impulse (ARFI) elastography, we measured the shear wave velocity (SWV) in different lesions of an elastography phantom with the convex 4C1 probe and the linea...
متن کاملQuantitative assessment of the masseter muscle's elasticity using Acoustic Radiation Force Impulse.
AIMS The study proposes Acoustic Radiation Force Impulse (ARFI) assessment of the masseter muscle elasticity in the healthy population and in patients who have undergone head and neck radiation therapy. PATIENTS AND METHODS Twenty-five healthy controls constituted group A, and 13 patients who had underwent radiotherapy (35Gy minimum) formed group B. ARFI was performed bilaterally in the perip...
