LOS ANGELES (Feb. 29, 2008) – Researchers at Cedars-Sinai Medical Center are developing a spectral imaging system that could result in shorter operating times for infants undergoing surgery for Hirschsprung’s disease, according to a mouse study reported in the Journal of Biophotonics. The study documents that in addition to its diagnostic potential, spectral imaging may provide an “optical biopsy,” allowing precise localization of a needed intervention.
