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 determine the intra-rater and inter-rater reliability of US measurements of meniscal protrusion with and without weight bearing.
The researchers are trying to see whether contrast-enhanced ultrasonography, shear wave elastography, strain imaging, and 3-D volume ultrasonography improves arterial wall visualization and identifies arterial elastic properties among individuals with fibromuscular dysplasia (FMD), atherosclerosis, personal history of spontaneous coronary artery dissections (SCAD), or personal history of segmental arterial mediolysis (SAM) that may be different compared to those without the aforementioned conditions.
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.
