-
Jacksonville, Fla.
The purpose of this study is to benchmark the feasibility of carotid artery biomechanical analysis and vertebral-basilar Transcranial Doppler (TCD) as markers of vascular involvement in presbyacusis and presbyvestibulopathy.
-
Rochester, Minn.
The purpose of this study is to see if using two-dimensional speckle tracking echocardiography improves the initial diagnosis of acute coronary syndrome in patients with chest pain who visit the emergency department.
-
Rochester, Minn.
The purpose of this study is to investigate hospitalized, non-ICU patients undergoing intermittent hemodialysis (HD) to determine:
- If the combined use of lung and intra-abdominal vessels ultrasound in volume assessment would be better for estimation of dry weight
- If the changes of the lung ultrasound B line numbers as well as portal venous flow pulsatility and IVC diameters could predict intra-dialytic manifestations and/or complications, such as hypotension, hypertension, tachycardia, and change in oxygen requirements
- If findings seen with a hand-held scanner are similar to a portable ultrasound scanner

Rochester, Minn.
Hypothesis: Identification of vulnerable atherosclerotic plaques (with or without neovascularization) using carotid CEUS is an independent predictor of MACE (over clinical risk factors, stress echo wall motion results, and carotid ultrasound two-dimensional speckle tracking strain indices).
Primary Aims:
-
Evaluate the diagnostic role of carotid CEUS and two-dimensional speckle tracking strain imaging for detection of carotid plaque:
- To determine the feasibility and safety of Carotid CEUS and Two-dimensional speckle tracking strain imaging SE .
- To determine if carotid CEUS and two-dimensional speckle tracking strain imaging findings are associated with coronary angiographic results in those patients undergoing clinically indicated cardiac catheterization.
- To determine the diagnostic accuracy of CEUS in identifying a vulnerable atherosclerotic plaque and neovascularization compared to carotid MRI, in a subset of patients.
-
Evaluate the prognostic role of carotid CEUS and two-dimensional speckle tracking strain imaging for prediction of MACE:
- To determine if plaque identification (with or without neovascularization) on Carotid CEUS SE can improve the overall prediction of MACE over stress echo results alone
- To determine if Carotid ultrasound two-dimensional speckle tracking strain indices can improve the overall prediction of MACE over stress echo results alone.
- To determine if the detection of plaque neovascularization by Carotid CEUS is an independent predictor of MACE (over clinical risk factors, stress echo wall motion results, and carotid ultrasound two-dimensional speckle tracking strain indices).
-
Rochester, Minn.
The purpose of this study is to determine if ultrasound surface wave elastography (USWE) produces different recording patterns in healthy and lymphadematous limbs, to establish the relationship between USWE recording values and stages of lymphedema, and to understand the correlation between USWE lymphedema evaluation and other tracking modalities.
-
Rochester, Minn.
The purpose of this study is to investigate the value of ultrasound imaging of tumor microvasculature and stiffness as new biomarkers for evaluation of liver tumor.
-
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.
-
Rochester, Minn.
The purpose of the study is to assess the Motion Compensation functionality on EPIQ ultrasound system in a clinical environment.
-
Rochester, Minn.
The primary purpose of this study is to assess the feasibility of performing lung and kidney and lung ultrasound elastography among patients with critical illness from different etiologies that could be associated with volume overload.
-
Rochester, Minn.
This is a Phase 0 clinical trial to evaluate a twinkling biopsy marker (Patent Application Title: Non-Metallic Ultrasound-Detectable Markers Patent Application No.: 62/903,078, Application Type: Provisional) for ultrasound conspicuity in patients with breast cancer and locally advanced disease involving the axillary lymph nodes.
