The applied research of shear wave elastography and superb microvascular imaging in pathological grading of breast invasive ductal carcinoma / 中华超声影像学杂志

ABSTRACT

Objective To discuss the application value of shear wave elastography (SWE) and superb microvascular imaging (SMI) in pathological grading of breast invasive ductal carcinoma (IDC).MethodsSixty patients with breast tumor were selected,which were totally 64 lesions.Before operation,SWE and SMI pattern were started to detect the lesions.And images in SWE and SMI pattern were saved.All lesions were proved to be IDC and pathological gradings were got according to the pathological result.The mean of Young′s modulus(AveT1) and maximum of Young′s modulus(AveT2) were recorded in SWE pattern,and degree of blood was recorded in SMI pattern followed Adler′s grading standard.Then differences of AveT1,AveT2 and degree of blood in different pathological grading of invasive ductal carcinoma were evaluated.Results ①In pathological grading 1 group,the average of AveT1 was (62.1±10.4)kPa,and the average of AveT2 was (93.0±20.1)kPa.In pathological grading 2 group,the average of AveT1 was (79.8±8.6)kPa,and the average of AveT2 was (120.6±18.7)kPa.In pathological grading 3 group,the average of AveT1 was (92.6±12.1)kPa,and the average of AveT2 was (137.3±21.5)kPa.The AveT1 and AveT2 were gradually growing with higher pathological grading of breast invasive ductal carcinoma,which were statistically significant (P<0.05).②In pathological grading 1 group,there were 7 cases in the degree of blood 0-Ⅰ and 14 in the degree of blood Ⅱ-Ⅲ.In pathological grading 2 group,there were 3 cases in the degree of blood 0-Ⅰ and 18 cases in the degree of blood Ⅱ-Ⅲ.In pathological grading 3 group,there were only 1 case in the degree of blood 0-Ⅰ and 21 cases in the degree of blood Ⅱ-Ⅲ.There were more lesions of rich blood with higher pathological grading of breast invasive ductal carcinoma,which was statistically significant (P<0.05).Conclusions There are differences of elastography and degree of blood in different pathological grading of breast invasive ductal carcinoma,SWE and SMI can prompt pathological grading and provide important clinical reference value.
