Acoustic Radiation Force Impulse Elastography for Focal Hepatic Tumors: Usefulness for Differentiating Hemangiomas from Malignant Tumors
OBJECTIVE The purpose of this study is to investigate whether acoustic radiation force impulse (ARFI) elastography with ARFI quantification and ARFI 2-dimensional (2D) imaging is useful for differentiating hepatic hemangiomas from malignant hepatic tumors. MATERIALS AND METHODS One-hundred-and-one tumors in 74 patients were included in this study: 28 hemangiomas, 26 hepatocellular carcinomas ...
متن کاملAcoustic radiation force impulse elastography in differentiating renal solid masses: a preliminary experience.
New diagnostic methods are required to diagnose renal mass. Thus, we assessed virtual tissue quantification (VTQ) of acoustic radiation force impulse (ARFI) elastography in differentiation of renal solid masses. Forty-two patients with renal masses were assessed by VTQ in terms of measurement of the shear wave velocity (SWV). The masses were divided into three groups. They were clear cell carci...
متن کاملHepatic and Splenic Acoustic Radiation Force Impulse Shear Wave Velocity Elastography in Children with Liver Disease Associated with Cystic Fibrosis
BACKGROUND Liver disease associated with cystic fibrosis (CFLD) is the second cause of mortality in these patients. The diagnosis is difficult because none of the available tests are specific enough. Noninvasive elastographic techniques have been proven to be useful to diagnose hepatic fibrosis. Acoustic radiation force impulse (ARFI) imaging is an elastography imaging system. The purpose of th...
متن کاملThe safety and feasibility of diagnostic acoustic radiation force impulse elastography used for eyes. A preliminary in vivo study.
AIMS To assess the safety and feasibility of acoustic radiation force impulse (ARFI) elastography in the eyes of rats. Material and methods: One hundred and twenty-six SD rats were divided into 7 groups. Group 1 was the control group and Group 2 to Group 7 were investigated by ARFI elastography using increased powers of 5%, 10%, 20%, 50%, and 100% and repetitions of 5 or 10. The changes of ocul...
متن کاملResonant acoustic radiation force optical coherence elastography.
We report on a resonant acoustic radiation force optical coherence elastography (ARF-OCE) technique that uses mechanical resonant frequency to characterize and identify tissues of different types. The linear dependency of the resonant frequency on the square root of Young's modulus was validated on silicone phantoms. Both the frequency response spectrum and the 3D imaging results from the agar ...
