was changed:
Breast echotexture refers to the background tissue composition seen on breast sonography, analogous to breast density/amount of fibroglandular tissue on mammography and MRI. There are three categories according to the BI-RADS lexicon is usually classified into three categories lexicon 1:
- homogeneous
:background echotexture – fat- the bulk of the breast is comprised of fat lobules and uniformly echogenic bands of connective tissue
- homogeneous
: fibroglandularbackground echotexture – fibroglandular- deep to a thin hypoechoic layer of subcutaneous fat, there is a thick zone of homogeneously echogenic fibroglandular tissue (with hypoechoic ducts interspersed)
- heterogeneous
- there are multiple areas of increased and decreased echogenicity, with shadowing at the fat-fibroglandular interfaces
These terms are only used in screening ultrasounds and not in the diagnostic setting. The implication of heterogeneous background echotexture is that it may interfere with the detection of small/subtle lesions 1. This pattern is more common in young patients and those with heterogeneously dense breasts on mammography 1.
