1. Determine the feasibility of measuring velocity of flow across a patent foramen ovale and using this Doppler spectrum to estimate left atrial pressures.
2. Correlate PFO velocity Doppler profile with the degree of diastolic dysfunction.
3. To Correlated PFO velocity and Doppler derived left atrial pressure with left atrial pressure measured during cardiac catheterization in a subset of (n=20) subjects for validation of this methodology.
The purpose of this study is to investigate the value of ultrasound imaging of microscopic blood vessels as a new biomarker for identifying the difference between benign and cancerous uterine pathologies, and to compare ultrasound imaging to the diagnostics of MRI and (if available), surgical pathology.
The purpose of this study is to evaluate an ultrasound technology that may be used to evaluate liver fibrosis.
The purpose of this study is to compare the use of ultrasound to traditional xrays to evaluate fracture healing over time in patients with radius/ulna (arm) fractures.
The purpose of this study is to compare the effectiveness of ultrasound with magnetic resonance (MR) enterography in the diagnosing and monitoring of Crohn's disease.
The purpose of this study is to investigate the value of ultrasound imaging of small blood vessels and tumor stiffness as a new biomarker to characterize the disease and evaluate early treatment for cancer.
Our goal is to determine if the stiffness of supraspinatus muscle can be measured non-invasively before surgery, using ultrasound B-mode together with a new ultrasound technique called Shear Wave Elastography (SWE). The hope is that this assessment of muscle stiffness before surgery will help the doctors to plan the best surgical approach.
This study evaluates the ability of ultrasound to measure the movement of tendons and nerves within the human carpal tunnel.
This study is being done to:
• Test an investigational stiffness measurement and imaging method on the lymph node found in the underarm area.
• Compare investigational imaging to sonography images.
• Compare investigational information to FDA approved US elasticity imaging conducted by SuperSonic Imaging (SSI) machine on the same lymph node in your underarm area.
• Compare to FDA approved ultrasound stiffness imaging system (GE Logiq E9)
• Compare to ultrasound images using Alpinion clinical ultrasound platform, FDA approved ECUBE 12and a non-FAD approved ECUBE 12R
The purpose of this study is to compare the accuracy of ultrasound to MRI for the diagnosis and characterization of tears in the ulnar collateral ligament (UCL) of the thumb.
