The efficacy of empirical parameter map based texture analysis as a method of predicting tumour response prior to neo-adjuvant chemotherapy is explored in a cohort of breast cancer patients with locally advanced disease. Analysis of washout slope maps revealed significant differences for 12 out of 16 textural parameters. Subsequent decision tree analysis utilised 5 parameters (f2, f3, f5, f11 and f16) obtaining a classification accuracy of 82%.
