digital breast tomosynthesis
Also written as: DBT — Digital Breast Tomosynthesis
Three-dimensional mammography technique that creates multiple thin-slice images of the breast to improve cancer detection.
Full Definition
Digital breast tomosynthesis is an advanced mammography technique that acquires multiple low-dose X-ray images of the breast from different angles to create a three-dimensional reconstruction. This technology reduces the masking effect of overlapping breast tissue, potentially improving cancer detection rates while reducing false positives and recall rates. DBT is particularly beneficial for women with dense breast tissue, where conventional mammography may be less effective. The technique requires specialized equipment and trained radiologists for interpretation.
Usage
Usage note: Often abbreviated as DBT in clinical documentation; distinguish from standard digital mammography.
