Breast MRI helps predict chemotherapy's effectiveness
Date:5/22/2012

ive benefit at the second MRI exam. MRI was better than clinical assessment in predicting both complete tumor response and residual cancer burden.

The study shows how imaging can play a vital role in characterizing a tumor and monitoring treatment response.

"What we see on imaging helps us define not just the size of the tumor but its biological activity," Dr. Hylton said. "We can observe if the signal increases after contrast injection, and interpret that increase as angiogenic activity. We can also use water diffusion measurements with MRI to provide an indirect reflection of the density of the cells."

Dr. Hylton and colleagues currently are assessing I-SPY data to see if MRI is better for predicting the likelihood of breast cancer recurrence. They expect to publish those results later this year.
