We have created this registry to provide an opportunity to study diagnostic capabilities, administration protocols and long-term effects of contrast-enhanced ultrasound (CEUS) of any organ.

The purpose of this study is to determine which new magnetic resonance sequences provide better, faster and more useful information. A sequence is a distinct method of obtaining magnetic resonance (MR) images. A magnetic resonance imaging (MRI) exam is made up of many different imaging sequences. These new sequences will be implemented on either on a 3 Tesla (3T) MR system, a 7 Tesla (7T) MR system (single- or multi- transmit), or both. Since the signal-to-noise ratio for MR images is highly dependent on the magnetic field strength, the anticipated signal-to-noise will be 7T greater than 3T and 3T greater than 1.5T systems. The 3T MR system is FDA approved whereas the 7T system is not FDA approved, but is built to the same standards as other FDA approved scanners. In addition, the FDA has approved magnetic field strength up to 8T for human imaging. Participants will be told ahead

The purpose of the study is to evaluate the impact of the Minimizing Text Complexity guidelines and tools and resources to support their use to increase access to the general education curriculum for students with significant cognitive disabilities.

We use an online conjoint experiment to study how diplomatic, military, and business elites formulate assessments of threat and opportunity in international politics.

We are administering a national survey to understand factors that shape US adults' views about the legitimacy of police.

Nationally, there is a shortage of geriatricians to meet the needs of an aging population. Geriatric medicine fellowship programs have difficulty filling all available clinical fellow physician positions each year. This survey-based survey seeks to understand factors that influence applicants' choice in a fellowship program.

EGID Partners is an online cohort of patients with eosinophilic gastrointestinal diseases (EGIDs), like eosinophilic esophagitis (EoE), eosinophilic gastritic (EG), eosinophilic gastroenteritis (EGE), and/or eosinophilic colitis (EC). It is a way to conduct important clinical research through surveys, and by filling out the initial survey, as well as follow-up surveys every 6 months, you can help answer important questions about living with EGIDs. We are also looking for people without EGIDs to provide information as well, so we can make comparisons between those do and don't have EGIDs. Adults as well as parents/caregivers of children are eligible. Find out more at www.egidpartners.org

The purpose of this study is to understand social perception.

The purpose of this study is to understand academic buoyancy in undergraduates at a rigorous university. College students face academic stress, burnout, depressive symptoms, and feelings of inadequacy. Findings will improve understanding of how students respond to academic stress and perceived inadequacy, and what they need to become academically buoyant.

We want to learn more about patients' experiences with hospital care at home compared to care in the hospital building. To do this, we will ask patients and families to complete a short survey and then connect their answers with existing medical records. This will help us understand the costs, challenges, and benefits of different types of hospital care.
