Research team develops tumor imaging system
By Elizabeth McNally | January 13, 2013Researchers from Dartmouth-Hitchcock Medical Center and the Thayer School of Engineering have developed a quantitative imaging system to detect low-grade brain cancer cells and make tumor removal more precise, according to Thayer School professor and research group co-leader Keith Paulsen. The technology consists of a drug, taken pre-operatively, which is broken down, processed and moved into brain tumor tissue. During surgery, the cancerous tissue fluoresces a pink color under a blue light, allowing neurosurgeons to remove the tumor more accurately, according to DHMC neurosurgeon and research group co-leader David Roberts. The fluorescent compound accumulates most intensely in high-grade brain tumor cells, which are not curable by surgery, according to Paulsen.
