Session attendees will learn about how slab reconstruction technology could help make digital breast tomosynthesis (DBT) exams more efficient.
In her presentation, Manisha Bahl, MD, from Massachusetts General Hospital in Boston, will discuss her team’s findings, showing how this technology reduces imaging volume and interpretation time without sacrificing diagnostic quality.
Standard DBT uses 1 mm slices, which leads to large image volumes and longer interpretation times compared to standard mammography. Slab reconstruction technologies generate thicker slices, which the researchers suggested could help address these challenges and lower storage needs. The team compared screening DBT performance results before and after this technology's implementation.
The study included 157,532 screening DBT exams in 81,416 women. Of these, the team included 89,218 exams in the preimplementation period and 68,314 exams in the postimplementation period.
The team reported that postimplementation metrics were on par with preimplementation results. This included cancer detection rates (6.6 vs. 6, respectively), sensitivity (87% vs. 82%), and false-negative rates (1 per 1,000 exams vs. 1.3 per 1,000 exams).
Slab technology implantation also led to a lower abnormal interpretation rate (5.9% vs. 6.6%, p < 0.001) and higher specificity (94.7% vs. 94%, p < 0.001) and positive predictive value (11.2% vs. 9.1%, p = 0.01).
Attend this session to see how these findings support broader integration of slab reconstruction tech into clinical practice.
