UltraCon: Harmonic motion imaging tracks breast tumor response to chemo

AUSTIN -- Harmonic motion imaging can track mechanical property changes of breast tumors in response to neoadjuvant chemotherapy, a study presented April 9 at UltraCon found. In his presentation, Yangpei Liu from Columbia University in New York City discussed findings from his team’s study, which showed that harmonic motion imaging could be a predictor of early treatment response. “Harmonic motion imaging-derives changes in tumor mechanical properties are more robust in early complete pathologic response prediction than tumor sizes,” Liu said.Yangpei Liu from Columbia University in Ney York City discussed findings at UltraCon suggesting that harmonic motion imaging could be a viable predictor of early treatment response.Amerigo Allegretto Breast imaging researchers have investigated different methods for monitoring tumor response to neoadjuvant chemotherapy to better predict which patients can avoid surgery. Liu said that while dynamic contrast-enhanced MRI, diffusion-weighted imaging, and PET/CT have shown that they can monitor functional tumor biomarkers in large masses, they suffer from low specificity. Elastography has also been explored in this area, but Liu said that this method is operator-dependent, tumor-size dependent, and relies on shear wave propagation in a locally homogenous region. Harmonic motion imaging, meanwhile, is an ultrasound-based elasticity imaging technique that uses oscillatory acoustic energy to estimate the mechanical properties of tiss...
