Abstract:
Objective:To discuss the applied value of the ultrasonic light scattering imaging DOT technology in the diagnosis of early breast lumps. Methods: The data of 114 patients that were experted ultrasound imaging of light scattering and were with clear pathological diagnosis results were analyzed retrospectively in our department in three years. Diagnostic indicators (SDI), the mass of the total amount of hemoglobin (HBT), oxygen saturation (SO2), mass direction (Orien) form factor (Forml) and the posterior echo (Pecho) were recorded, and the diagnostic sensitivity, specificity, positive predictive value, negative predictive value, false negative rate and false positive rate were analyzed. The results were proceed and analyzed through SPSS 17.0. Results:There were significant differences in the SDI, HBT, Orien, Forml(t=-4.122,t=-2.275,t=-2.206,t=-2.927,P<0.05)The diagnostic sensitivity was 95.7%, specificity was 95.5%, positive predictive value was 93.8%, negative predictive value was 97.0%,false negative rate was 4.3%and false positive rate was 4.5%. Conclusion: Light scattering of ultrasound imaging use SDI, HBT, Orien, the Forml four quantitative indicators, qualitative evaluation can reach the masses, has a higher value in the differential diagnosis.
