Clinical Studies

Identification and Differentiation of Thyroid Nodules by Acoustic Imaging and Viscoelastic Parameters Rochester, Minn.
The purpose of this research study is to evaluate imaging methods for detection and differentiation of thyroid nodules.

External Evaluation Plan: GE Ultrasound System Performance Evaluation Scottsdale/Phoenix, Ariz.
The purpose of this study is to evaluate the performance of the investigational GE Ultrasound Systems including image quality, under clinical conditions and to obtain feedback from experienced users.
Identification and Differentiation of Thyroid Nodules by Acoustic Imaging and Viscoelastic Parameters Scottsdale/Phoenix, Ariz.
The purpose of this research study is to evaluate imaging methods for detection and differentiation of thyroid nodules.
Measurement of Renal Viscoelastic Properties with Ultrasound (KSS-Kidney Stiffness Study) Rochester, Minn., Scottsdale/Phoenix, Ariz., Jacksonville, Fla.
The purpose of this study is to obtain knowledge of the viscoelastic material properties of the kidney in healthy individuals, patients with chronic kidney disease, and patients who have received a kidney transplant. The aim of the study is to evaluate if these properties are unique indicators of renal health.
Quantitative Assessment of Skin and Liver of Patients with Diffuse Systemic Sclerosis Using Shear-Wave Ultrasound Elastography (SWE) Scottsdale/Phoenix, Ariz.
This study aims to evaluate if the skin thickness (the measurement of the dermis) or stiffness as part of the US-SWE exam as we can see it on grayscale US differs between SSc patients and controls and to evaluate if there is associated liver stiffness by US-SWE in patients with SSc as compared to controls.
