简要总结
Objective: To explore the potential association between the multimodal ultrasound characteristics and pathological classification of BI-RADS category 4 breast lesions, so as to clarify the diagnostic characteristics of multimodal ultrasound in different pathological types BI-RADS category 4 breast lesions.
Materials and methods: Patients who visited in The First Affiliated Hospital of Shandong First Medical University ＆ Shandong Provincial Qianfoshan Hospital were collected. Their general clinical features, information on preoperative ultrasound diagnosis, and postoperative pathologic data were reviewed.
