Acoustic radiation force impulse induced strain elastography and point shear wave elastography for evaluation of thyroid nodules.
The aim of the study was to evaluate the diagnostic performance of acoustic radiation force impulse (ARFI) induced strain elastography (SE), point shear wave elastography (p-SWE), and their combined use in differentiating thyroid nodules. This retrospective study included 155 thyroid nodules (94 benign and 61 malignant) in 136 patients. Ultrasound, ARFI-induced SE and p-SWE were performed on ea...
متن کاملMeasuring shear-wave speed with point shear-wave elastography and MR elastography: a phantom study
OBJECTIVES To compare shear-wave speed (SWS) measured by ultrasound-based point shear-wave elastography (pSWE) and MR elastography (MRE) on phantoms with a known shear modulus, and to assess method validity and variability. METHODS 5 homogeneous phantoms of different stiffnesses were made. Shear modulus was measured by a rheometer, and this value was used as the standard. 10 SWS measurements ...
متن کاملComparison of Diagnostic Accuracy of Real-Time Elastography and Shear Wave Elastography in Differentiation Malignant From Benign Thyroid Nodules
Thyroid nodules are relatively more prevalent in iodine-deficiency area, and the incidence increased sharply in the past decade in these areas. Workup of malignant from benign nodules in clinic was the main problem for managing thyroid nodules.An overall search for the articles about the diagnostic performance of real-time elastography (RTE) and shear wave elastography (SWE) before April 2015 i...
متن کاملComparative study between two point Shear Wave Elastographic techniques: Acoustic Radiation Force Impulse (ARFI) elastography and ElastPQ.
AIM To compare the feasibility and the liver stiffness (LS) values obtained by means of the two available point Shear Wave Elastographic (pSWE) techniques: ARFI elastography and ElastPQ technique. MATERIAL AND METHODS Our study included 176 subjects with or without chronic liver disease, in which LS was evaluated in the same session by means of ARFI elastography and ElastPQ. RESULTS Ten val...
متن کاملShear wave elastography using amplitude-modulated acoustic radiation force and phase-sensitive optical coherence tomography.
Investigating the elasticity of ocular tissue (cornea and intraocular lens) could help the understanding and management of pathologies related to biomechanical deficiency. In previous studies, we introduced a setup based on optical coherence tomography for shear wave elastography (SWE) with high resolution and high sensitivity. SWE determines tissue stiffness from the propagation speed of shear...
