Study Summary
The purpose of this study is to test a method of imaging (taking a picture) of the abdomen (belly), neck, thigh and calf (lower leg) areas of the body, using ultrasound along with a drug which makes the pictures look clearer. Ultrasound is a type of imaging that uses sound waves to create a picture of the inside of the human body. Two sets of pictures will be taken on two different days to see if the results are the same each time. DEFINITY® is a drug given intravenously (through the vein). DEFINITY® is approved by the FDA to be used as an ultrasound contrast agent (makes the pictures look clearer) while taking pictures of the heart. In this study, DEFINITY® will be used while taking pictures of blood vessels in your abdomen (belly), neck, thigh and calf (lower leg). Since this use of DEFINITY® is different than the use approved by the FDA, this study will be performed under an FDA Investigational New Drug (IND) application.
Primary Outcome
The variability of repeated measures for each subject, expressed as coefficient of variation (CV), in the periadventitial microvascular flow, subcutaneous microvascular flow and skeletal muscle flow.
