Very. As long as the portable ultrasound screening program is icavl accredited, the results will be 90%-98% accurate.

Intersocietal commission for the accreditation of vascular laboratories.
Dependable. Most ultrasound screening programs are reliable. This technology is dependent on the technician and the speciality of the lab. An accredited lab that has registered technologists should be reliable. In any event a confirmatory test such as a ct angiogram may be indicated if the results i the ultrasound are questionable.
Accurate. Good technology.
