Washington, Oct 22 : Radiologists can now use three-dimensional (3-D) power Doppler ultrasound to differentiate between malignant and benign breast cancer cells, according to a new study.

Usually, malignant breast masses have increased blood flow compared to normal tissue or benign masses.

The study has found that using 3-D power Doppler ultrasound can make it is possible to detect vessels with higher flow speeds, which likely indicate cancer.

"Using 3-D scans promises greater accuracy due to more consistent sampling over the entire tumor," said lead author, Gerald L. LeCarpentier, Ph. D., assistant professor in the Department of Radiology at University of Michigan in Ann Arbor.

Washington, Oct 22 : A research team, involving an Indian origin scientist, has developed a new self-assembling hydrogel drug delivery system that can ill not only deliver clinically approved drugs in high concentrations, but also do away with any toxic residue in the process.
