Abstract
The present invention relates to a method for quantifying drug delivery with the characteristic of measuring the signal intensity of peripheral vessels with a contrast-enhanced ultrasound to quantify the drug delivery at a target site. The present invention can be used for quantifying UTMD (ultrasound triggered microbubble destruction) targeted drug delivery, also for qualifying the unreleased amount of the long-acting drug in the tested object, and for helping setting the treatment schedule for ultrasound disruption of blood-brain barrier.
