Technology May Help Surgeons Tell Brain Cancer From Healthy Tissue

HealthDay news image

 

Researchers are making progress in developing an ultrasound-like technology that helps brain surgeons distinguish between brain tumors and normal tissue.

In the new study, researchers report how the technology worked on human brain tissue. But, the technology hasn't yet been tested in living people.

"Hopefully this summer we'll unroll the first preliminary studies, and we'll begin to use it in patients," said study co-author Dr. Alfredo Quinones-Hinojosa, professor of neurological surgery and oncology and director of the Brain Tumor Surgery Program at Johns Hopkins University School of Medicine in Baltimore. Currently, he said, "we agonize because many times we can't tell what is tumor and what is normal brain."

The study appears in the June 17 issue of Science Translational Medicine.
