Liu tracks oxygen in the body


May 8, 2014

Measuring tumors’ oxygen levels could help doctors make decisions about treatments, but there’s currently no reliable, noninvasive way to make such measurements. However, a new sensor developed at MIT could change that: A research team led by professor Michael Cima has invented an injectable device that reveals oxygen levels over several weeks and can be read with magnetic resonance imaging (MRI).

Using this kind of sensor, doctors may be able to better determine radiation doses and to monitor whether treatments are having the desired effect, according to the researchers, who describe the device in the Proceedings of the National Academy of Sciences the week of April 21.

“In cases where you are trying to make therapeutic decisions, you want to have some numbers that you can fall back on,” says Vincent Liu, a graduate student in Cima’s lab at MIT’s Koch Institute for Integrative Cancer Research and lead author of the paper.
