Abstract

Background and purpose: Tissue differentiation based on measurement of ultrasonic parameters is an ideal gool. In this study, attenuation coefficent measurement in 10 MHZ ultrasonic wave in BREAST tissue, begin and maliguant paranchymal tissue at 20°c, 25°c, 30°c and 35°c were measured and analyzed.Materials and methods: Data were collected from 57 biopsies and mastectomy specimens, then implanted in medium having the same condition of BREAST paranclaymal tissue, then ultrasonic images (A-mode) at 20 c, 25 c, 30 c and 35 c were recorded and processed. After measuring of ecostatistic resistant and study of echo ranges from frontal and posterior sections of the specimens, ATTENUATION COEFFICIENT was determined.Results: The results showed that, at under, 37°c, with increasing in TEMPERATURE, ATTENUATION COEFFICIENT has negative dependence to the increase in TEMPERATURE. Value of ATTENUATION COEFFICIENT at 20°c for normal paranchymal tissues begin and malignant tissue are about 26.7%, 16.8% and 17.4% respectively, which are higher than that of 35°c. by measuring of ATTENUATION COEFFICIENT of ultrasonic wave in the groups under study, it was noticed that, there is significant statistical difference (P<0.005) of ATTENUATION COEFFICIENT among parenchymal, benign and malignant tissues at all different TEMPERATUREs under study.Conclusion: Application of the obtained results in presentation of differential diagnostic procedures for the lesions is discussed.
