ABUS useful as DBT adjunct in screening, diagnostic imaging

Automated breast ultrasound (ABUS) is useful as an adjunct to digital breast tomosynthesis (DBT) in opportunistic screening and diagnostic imaging, suggest findings published October 14 in Ultrasound in Medicine & Biology.  A team led by Kartini Rahmat, MBBS, from Universiti Malaya in Kuala Lumpur, Malaysia found that when ABUS and DBT were added to the screening population of its study, the biopsy rate was about 23%. The cancer detection yield from both modalities was just over 9% for both screening and diagnostic groups. “The results from our study can be applied in countries with no population screening," the Rahmat team wrote. DBT continues to be studied as more breast imaging facilities adopt the technology. Previous studies suggest that using DBT over 2D mammography results in an overall reduction in recall rate and an increase in cancer detection rate. However, the technology still contends with the challenge of imaging dense breasts, with women having extremely dense breasts being at higher risk. Previous studies have also highlighted the capabilities of ABUS to further identify additional invasive cancers, which tend to be small and node-negative. The researchers noted that ABUS overcomes conventional ultrasound’s weakness of being user-dependent while detecting breast cancers masked by dense breast tissue. Rahmat and colleagues sought to assess the diagnostic performance of ABUS as an adjunct to DBT in both breast cancer screening and diagnostic imaging....
