I was going through some articles and mail this morning and found a peice written last year in Science Daily regarding targeted delivery and micro-bubbles. I think it would be beneficial to post it again.
ScienceDaily (Jul. 13, 2007) — A new targeted drug delivery method uses ultrasound to image tumors, while also releasing the drug from "nanobubbles" into the tumor, according to a study published online July 10 in the Journal of the National Cancer Institute.
One other post from the ARMDS newsletter is worthy of a read concerning a new form of ultrasound technology designed to screen out reverberation artifacts. The authors claim this will allow better screening for small tumors of the prostate, breast and thyroid among other things. The article is translated (supposedly) from Dutch. It will be interesting to see which manufacturer snaps this new technology up.
ScienceDaily (Mar. 4, 2008) — New ultrasound technology will make it possible for doctors to discover cancer tumors far earlier than before. A method that transmits new and more advanced ultrasound signals is being tested in Trondheim. The chances of discovering and diagnosing tumors in the prostate and breast are expected to improve significantly.
