Measure
Perflutren Lipid Microsphere (Healthy Subjects)
Healthy subjects will be imaged using contrast-enhanced ultrasound (perflutren) for image optimization prior to enrolling clinical patients. Perflutren Lipid microsphere: Perflutren will be administered in a bolus or continuous infusion using the dosing range and administration type within the perflutren prescribing information.Once perflutren lipid has been administered, the transducer is maintained in a constant position over the area of interest to show the target lesion in order to assess the enhancement pattern during the early, mid and late vascular phases. Images will also be taken of kidney parenchyma in a suitable longitudinal plane.If there are multiple lesions in one subject requiring a second dose, the subject will have the option to undergo a 2nd contrast-enhanced study 30-minutes after the initial contrast dose, per dosing instructions in the package insert.
