Abstract

Ultrasound propagation VELOCITY was measured experimentally in normal, benign and malignant breast tissues at various temperatures from 20 through 35°C, in order to distinguish tumors from normal breast tissue. In quantitative measurements of ultrasound VELOCITY, 57 breast tissue specimens were selected, comprising 17 normal breast tissues, 20 benigns, and 20 malignant tumors. The cases were implanted in breast tissue mimicking materials and ultrasonic images (A-mode) at 20, 25, 30 and 35°C were processed and evaluated. It was observed that ultrasound propagation VELOCITY in various temperatures is an important factor to distinguish in vitro specimens of benign and malignant from normal tissue (P-value<0.005). However, ultrasound velocities in malignant and benign tumors were very similar with almost complete overlap in all the temperatures. Evaluation of ultrasound velocities in all the temperatures showed that in normal breast tissue, benign and malignant tumors, ultrasound VELOCITY increases with temperature linearly. In 20˚C, ultrasound velocities in benign and malignant specimens were differentiated slightly. Therefore, the results show the measurement of ultrasound velocities in normal breast tissue and malignant and benign tumors can be used in differentiation of tissues.
