ABSTRACT
Objective The article was to discuss the correlation between three?dimensional volume ultrasound VOCAL parame?ters and pathological grading of mass type breast invasive ductal carcinoma. Methods 106 breast nodule patients admitted in our hospi?tal who were pathologically confirmed with histological grading from March 2014 to February 2016 were included in the study. The patients underwent three?dimensional volume ultrasound preoperatively. Vocal system in GE LOGIQ E9 was used in lesion analysis to obtain energy histograms:average gray scale (MG), average energy (MP), vascular index ( R) , blood flow index ( VFI) . Analysis was made in the differ?ence among MG, MP, R and VFI of ductal carcinoma in situ, invasive ductal carcinoma grade I, invasive ductal carcinoma grade II, invasive ductal carcinoma grade III and fibroadenoma. Results No sig?nificant difference was found in MG of ductal carcinoma in situ and IDC I, fibroadenoma and ductal carcinoma in situ, fibroadenoma and IDC I(P>0.05), but the difference was statistically significant between other pathological levels (P0.05) , but the difference was statistically significant between other pathological levels ( P<0.05) . Conclusion Three?dimensional volume ultrasonic VOCAL parameters of MG、MP、R、VFI can reflect gray?scale levels and blood flow perfusion in mass type breast nodules of different pathological level, and predict the pathological grading before operation, which provides objective evidence for the evaluation of mass type breast invasive ductal carcinoma and the development of individualized treatment plan.
