Imaging method gives early indication if brain cancer therapy is effective
April 19th, 2005
A special type of MRI scan that measures the flow of water molecules through the brain can help doctors determine early in the course of brain cancer therapy if a patient's tumor will shrink, a new study shows. Researchers at the University of Michigan (U-M) Comprehensive Cancer Center developed the assessment, which they call a functional diffusion map. They used a magnetic resonance imaging scan that tracks the diffusion, or movement, of water through the brain and mapped the changes in diffusion from the start of therapy to 3 weeks later. The tumor cells block the flow of water, so as those cells die, water diffusion changes. In the study of 20...
