Molecular Imaging Allows Individualized 'Dose Painting' for Head and Neck Cancers

Posted 06-14-2010 at 06:20 PM by admin

ScienceDaily (June 14, 2010) — According to research revealed at the Society of Nuclear Medicine's 57th Annual Meeting, a multi-tracer molecular imaging technique using positron emission tomography (PET) provides detailed information about the physiological processes of cancerous tumors -- and could one day help radiation oncologists treat head and neck cancers with precision external-beam radiation therapy and improve the outcomes of therapy.

"The research that we are conducting with Philips is extending the use of molecular imaging for radiotherapy planning, moving closer to more personalized treatment of hard-to-treat cancers based on the biology of each individual patient's tumor," said Kristi Hendrickson, Ph.D., lead author of the study and medical physicist at the University of Washington Medical Center, Seattle, Wash. "By modeling the data acquired from PET scans, we can potentially reduce damage to surrounding healthy tissue, as well as provide the ability to do 'dose painting,' delivering a highly customized form of radiation therapy for each patient."
