et al.

Abstract: ObjectivesHere we report on the intra‐ and inter‐operator variability of the backscatter coefficient (BSC) estimated with a new low‐variance quantitative ultrasound (QUS) approach applied to breast lesions in vivo.MethodsRadiofrequency (RF) echo signals were acquired from 29 BIRADS 4 and 5 breast lesions in 2 sequential cohorts following 2 imaging protocols: cohort 1) radial and antiradial views, and cohort 2) short‐ and long‐axis views. Protocol 2 was implemented after retraining and discussion on how to impr… Show more

“…13 As observed in our study, and echoed in oncology research, QUS has the ability to characterize lesions and reduce the variation in common clinical diagnoses. 26,[51][52][53] In essence, 3D QUS imaging can become an indispensable clinical imaging modality to enhance our knowledge of placental development, function and related malignancies.…”
