The study included 27 patients who had increased levels of prostate specific antigen after being treated with high-intensity focused ultrasonic (HIFU) ablation; 18 of these patients had local tumor progression seen at biopsy. DCE-MRI and DWI had about a 72% accuracy rate in determining which patients needed additional treatment because they had residual or recurrent cancer, said Chan Kyo Kim, MD, lead author of the study. The study found that DWI had fewer false positives than DCE-MRI, but DCE-MRI had fewer false negatives.
“After HIFU ablation, the normal anatomy of the prostate gland is completely lost or deformed making it difficult to distinguish benign tissue from cancer,” said Dr. Kim. The two imaging studies together, which can be done in about seven minutes, can overcome that challenge, he said.
HIFU is becoming more common as a prostate cancer treatment option, particularly for those persons who can’t or don’t want to undergo a radical prostatectomy, said Dr. Kim.

Soft robots have a distinct advantage over their rigid forebears: they can adapt to complex environments, handle fragile objects and interact safely with humans. Made from silicone, rubber or other stretchable polymers, they are ideal for use in rehabilitation exoskeletons and robotic clothing. Soft bio-inspired robots could one day be deployed to explore remote or dangerous environments.
Most soft robots are actuated by rigid, noisy pumps that push fluids into the machines' moving parts. Because they are connected to these bulky pumps by tubes,...

Over the next three years, researchers from the Vrije Universiteit Brussel, University of Cambridge, École Supérieure de Physique et de Chimie Industrielles de la ville de Paris (ESPCI-Paris) and Empa will be working together with the Dutch Polymer manufacturer SupraPolix on the next generation of robots: (soft) robots that ‘feel pain’ and heal themselves. The partners can count on 3 million Euro in support from the European Commission.
Soon robots will not only be found in factories and laboratories, but will be assisting us in our immediate environment. They will help us in the household, to...
