Abstract：Objective To analyze the diagnostic value of each characteristic ultrasound image in breast invasive ductal carcinomas.Methods One hundred and thirty-five patients with invasive ductal carcinomas of the breast admitted to our hospital between January 2018 and December 2019 were included in this study to analyze the characteristics of ultrasound image of breast infiltrating ductal carcinomas, the detection rate of self-examination and the correlations between lymph node metastasis and lesion size and location.Results (1)Singe factor analysis showed that such ultrasound imaging features as an irregular shape (91.00%), unclear borders (91.00%), blood flow signals (77.78%), microcalcification (55.56%), aspect ratio>1 (26.67%), and posterior echo attenuation (15.50%) were correlated with the diagnosis with invasive ductal carcinomas.(2)Invasive ductal carcinomas in the inner and upper quadrants were more likely to be detected by the patient's self-examinationthan the other three quadrants, accounting for 54.00% of the cases detected by self-examination.(3)Infiltrating ductal carcinomas in the inner and upper quadrants were more prone to lymph node metastasis (metastasis rate: inner upper: 36.40%, inner lower: 0%, outer upper: 50.00%, outer lower: 16.67%).(4)The size of invasive ductal carcinomas was not related to the metastasis of axillary lymph nodes.Conclusions Ultrasound has a strong ability to detect breast lesions. An irregular shape in the ultrasound image is most likely to be a sign of an invasive ductal carcinoma of the breast, and it is manifested in early lesions. The self-detection rate of breast lesions and the lymphatic metastasis rate of breast cancer are closely related to the size and location of breast lesions.
