1. A Study to Determine the Feasibility of Doppler Ultrasound of Large Arterial Systems of the Brain as Vascular Involvement Markers in Presbyacusis and Presbyvestibulopathy

   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.

2. A Study to Evaluate the Use of Lung and intra-abdominal vessels Ultrasond for Intradialytic Complications in Hospitalized Patients on Intermittent Hemodialysis

   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

3. A Study to Evaluate Liver Tumors with Ultrasound Microvessel Imaging and Shear Wave Elastography

   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.

4. A Study to Evaluate the GE Ultrasound System Performance

   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.

5. A Motion Compensation Study

   Rochester, Minn.

   The purpose of the study is to assess the Motion Compensation functionality on EPIQ ultrasound system in a clinical environment.

6. A Study to Evaluate Noninvasive Ultrasound Elastography of Kidney and Lung in Assessment of Volume Status in ICU Patients

   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.

7. Mayo Biopsy Marker

   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.

8. A Study to Compare Two Ultrasound-based Methods for Assessing Diaphragm Muscle Function

   Rochester, Minn.

   The purpose of this study is to assess and compare the utility of ultrasonographic shear wave elastography (SWE) method as compared to “ABCDE” thickening ratio and fraction method in assessing diaphragm function.
