This study is designed to evaluate the technical performance and clinical handling of a coronary catheter that includes two imaging techniques. The catheter being evaluated performs near ...
The primary objective of this study is to compare the lumbar proprioception of patients with chronic back pain to that of healthy volunteers during low- and high-frequency muscle vibration...
The purpose of this research study is to test a new medical device, called SONAS. The SONAS device is a portable, battery-powered ultrasound device to detect strokes in the prehospital env...
This research study is being done to collect data and analyze the motion of soft tissue in the abdomen (liver, pancreas, stomach and intestines) of people who have pancreatic and liver can...
This study will assess the feasibility of remotely guided US use by individuals without ultrasound training to assess for normal lung parenchyma in healthy volunteers. The untrained operat...
The pharmacokinetics (PK) of β-lactam antibiotics in cystic fibrosis (CF) patients has been compared with that in healthy volunteers for over four decades; however, no quantitative models exist that ...
Adequate preoperative fasting is critical in preventing pulmonary aspiration of gastric content. We proposed to study the sonographic gastric content dynamics after the ingestion of liquid or solid fo...
When using high-frequency (HF) ultrasound in sonography, attenuation due to the viscosity of the medium limits the available imaging depth, and strong reflection and scattering from hard tissue, such ...
As with all early-stage testing of investigational drugs, clinical trials targeting HIV/AIDS can pose unknown risks to research subjects. Unlike sick participants seeking a therapeutic benefit, the mo...
Purpose To investigate the relationship between abdominopelvic magnetic resonance (MR) imaging and formation of DNA double-strand breaks (DSBs) in peripheral blood lymphocytes among a cohort of health...
Persons with no known significant health problems who are recruited to participate in research to test a new drug, device, or intervention as controls for a patient group. (from http://clinicalcenter.nih.gov/recruit/volunteers.html, accessed 2/14/2013)
Ultrasonography applying the Doppler effect, with frequency-shifted ultrasound reflections produced by moving targets (usually red blood cells) in the bloodstream along the ultrasound axis in direct proportion to the velocity of movement of the targets, to determine both direction and velocity of blood flow. (Stedman, 25th ed)
Hospital or other institutional ethics committees established to consider the ethical dimensions of patient care. Distinguish from ETHICS COMMITTEES, RESEARCH, which are established to monitor the welfare of patients or healthy volunteers participating in research studies.
Spectroscopy technique which measures changes in organic compounds by tracking the spectral energy of absorption of HYDROGEN atoms.
Human experimentation that is not intended to benefit the subjects on whom it is performed. Phase I drug studies (CLINICAL TRIALS, PHASE I AS TOPIC) and research involving healthy volunteers are examples of nontherapeutic human experimentation.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
