Ultrasound to locate hyaluronic acid filler?

i got this info from the NIH and they say hyaluronic acid fillers are visible through ultrasound. issue is where do i find someone who can do and analyze ultrasound to locate filler to be dissolved? from NIH.gov "filler material was clearly visible with the ultrasound and subsequently measurable in each scan. Each scan procedure was completed within a short time period meaning quantitative data could be acquired with minimum trauma to the volunteer."
