Leesburg, VA - According to an article in ARRS' American Journal of Roentgenology (AJR), digital breast tomosynthesis (DBT) spot compression view could help characterize equivocal DBT findings, thus reducing further workup for benign findings.

Noting that DBT spot compression increased both intrareader and interreader agreement and improved diagnostic accuracy, primarily from improved specificity, "the view's supplemental dose was slightly higher than that of a standard DBT view," corresponding author Foucauld Chamming's of Institut Bergonié in Bordeaux, France acknowledged.

The all-French team's retrospective study included 102 women (mean age, 60 years) for whom a DBT spot compression was acquired to characterize an equivocal finding on DBT (via the performing radiologist's discretion) from December 14, 2018 to December 18, 2019. Conscious of the equivocal lesions' location, two fellowship-trained breast radiologists and one breast imaging fellow independently reviewed all examinations—assigning an initial BI-RADS category using standard DBT views, immediately followed by a category using DBT spot compression.

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.

North America's first radiological society, the American Roentgen Ray Society (ARRS) remains dedicated to the advancement of medicine through the profession of medical imaging and its allied sciences. An international forum for progress in radiology since the discovery of the x-ray, ARRS maintains its mission of improving health through a community committed to advancing knowledge and skills with the world's longest continuously published radiology journal—American Journal of Roentgenology—the ARRS Annual Meeting, InPractice magazine, topical symposia, myriad multimedia educational materials, as well as awarding scholarships via The Roentgen Fund®.
