Mayo Clinic researchers are studying ways to improve the effectiveness of prostate brachytherapy.

The effectiveness of permanent prostate brachytherapy depends on how the radioactive seeds are distributed. Researchers at Mayo Clinic study imaging techniques to improve the results of permanent prostate brachytherapy treatment. They have conducted tests on human tissue that produce clear, 3-D images of the prostate within a few minutes.


Vibro-acoustography uses high-energy sound waves (ultrasound) to cause tissue to vibrate. Cancerous tissue is harder (denser) than normal tissue, and vibro-acoustography is particularly sensitive to hard objects. Vibro-acoustography makes it possible to place brachytherapy seeds, check their position and correct placement in one procedure.


See a list of publications from Mayo Clinic doctors on permanent prostate brachytherapy on PubMed, a service of the National Library of Medicine.
