Digital breast tomosynthesis spot compression clarifies ambiguous DBT findings

Based on kappa coefficients for DBT with and without spot compression views, intrareader agreement increased from 0.43 to 0.72, and interreader agreement increased from 0.21 to 0.45. Additionally, for all three readers, DBT spot compression views yielded significantly increased accuracy, as well as significantly increased specificity.

Adding that their study is the first to evaluate the impact of obtaining DBT spot compression for equivocal findings on DBT, "the results support the utility of spot compression views for aiding evaluation of subtle or ambiguous findings encountered on DBT in clinical practice," the authors of this AJR article concluded.
