B-Mode and Acoustic Radiation Force Impulse (ARFI) Imaging of Prostate Zonal Anatomy

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...

Role of Acoustic Radiation Force Impulse (ARFI) Elastography in Determination of Severity of Benign Prostate Hyperplasia

BACKGROUND The aim of this study was to investigate the potential contribution of acoustic radiation force impulse (ARFI) elastography to the determination of the severity of benign prostate hypertrophy (BPH) by performing shear wave velocity (SWV) measurements of the prostate using ARFI technology. MATERIAL AND METHODS Sixty BPH patients and 40 healthy volunteers were included in this study. S...

In Vivo Study of Transverse Carpal Ligament Stiffness Using Acoustic Radiation Force Impulse (ARFI) Imaging

The transverse carpal ligament (TCL) forms the volar boundary of the carpal tunnel and may provide mechanical constraint to the median nerve, leading to carpal tunnel syndrome. Therefore, the mechanical properties of the TCL are essential to better understand the etiology of carpal tunnel syndrome. The purpose of this study was to investigate the in vivo TCL stiffness using acoustic radiation f...

Achilles 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...
