Something Old, Something New

Greetings,

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.

Intracranial monitoring with ultrasound

Greetings all,

I new interest in intra-operative monitoring during enarterectomy is re-visited. I will post a couple of interesting links.

A-Mode Echoencephalography

Eric Blackwell, MD OBGYN.net Editorial Advisor

"I would like to share with you a few words about the use of a-mode ultrasound (echoencephalography) at Bowman Gray. My training began several years before the ready availability of computed tomography in the emergency center setting. An early application of ultrasound was for rapid screening of trauma and stroke patients for intracranial mass lesions. The underlying concept was that a-mode ultrasound could be used to identify structures normally located in the midline of the brain such as the third ventricle and falx cerebri."

The second reference is from the ARDMS newsletter.

" New techniques for detecting harmful blood clots and air bubbles in arteriesNew techniques for detecting emboli have played a major role in dramatically reducing stroke rates after carotid edarterectomy.New techniques for detecting emboli (harmful blood clots/air bubbles in arteries) developed at the University of Leicester have played a major role in dramatically reducing stroke rates after carotid endarterectomy. This is an operation designed to remove narrowings in the main arteries supplying the brain before they can cause a stroke."
