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.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
