Adding DBT to full-field digital mammography has been shown to lower recall rates and improve cancer detection; however, it takes significantly longer to read a DBT study, according to presenter Dr. Emily Conant of the Hospital of the University of Pennsylvania in Philadelphia. The researchers sought to determine whether AI software from iCAD -- currently pending U.S. Food and Drug Administration clearance -- could reduce reading time in interpreting DBT studies while maintaining or improving radiologist performance.
In a reader study involving 24 radiologists reading 260 DBT cases both with and without AI, the radiologists realized a 5.7% improvement in the area under the receiver operating characteristic curve, an 8% increase in sensitivity, a 6.9% increase in specificity, and a 7.2% reduction in recall rate with the use of AI. What's more, reading times were shortened by 52.7%.
"Therefore, reading 2D [mammography] plus DBT with AI improved the readers' performance while also reducing reading time compared to reading without AI," Conant told AuntMinnie.com.
