Purpose The goal of this study was to investigate the use of measuring ultrasonic backscattered spectral centroid shift (SCS) to evaluate tumor early response to chemotherapy.Material and methods Experiments were approved by the regional animal care committee.Subcutaneous MCF-7 breast cancer bearing mice were treated with different dose of cisplatin in group B (1mg/kg, n =21) and group C (3mg/kg, n =22).A control group A was given with sterile saline (n =25).Ultrasonic radio-frequency (RF) data was collected with a clinical ultrasound scanner before treatment and on days 3 and 6 of the treatment.
