Summary

1\. Efficacy of PULSAR preoperative radiation 2. Evaluate potential of microbubble CEUS as an alternative to operative SLNBx 3. Evaluate potential of OA to evaluate treatment response of pre-operative radiation on the tumor

Conditions

Interventions

RADIATION

Radiomics on MRI

Through extracting and analyzing a large number of features from medical imaging, radiomics has shown promising results in treatment outcome prediction for many diseases including breast cancer (45-50). UTSW physics group has developed several new radiomic approaches and radiomic features, such as a multi-objective radiomics model(51) and a new radiomic "Shell" feature(52). As an exploratory end point for this trial, the investigators will explore the application radiomics using pre-treatment MRI, treatment parameters and clinical characteristics as input to predict pathological response of radiation therapy (XRT) based on pathology report of surgical tissues and local recurrence.
