All trials were prospective. The detection rate increased in all studies using DBT, especially of invasive cancers. Chose the correct answer regarding DBT screening trials conducted in Europe and the U.S. Knowledge Check Select the best answer. All trials were retrospective. Knowledge Check Correct Incorrect The solution is: The detection rate increased in all studies using DBT, especially of invasive cancers. Incorrect The solution is: The detection rate increased in all studies using DBT, especially of invasive cancers. Incorrect The solution is: The detection rate increased in all studies using DBT, especially of invasive cancers. Correct The solution is: The detection rate increased in all studies using DBT, especially of invasive cancers. Explanation of the Correct Answer Continue The study designs of the various DBT screening studies differ a lot but all studies share the finding that detection rate increased significantly. Explanation of the Correct Answer Requirements Requirements Prof. Dr. Chantal Van Ongeval University Hospital Leuven, Belgium Requirements 07-1_DBT-in-Screening_04-Requirements_V02.mp4 Use only one-view DBT (MLO). Discuss single reading instead of double reading. Try slab reconstruction. All answers describe useful approaches to reducing reading time when screening with DBT. These are all approaches for reducing reading time when screening with digital breast tomosynthesis (DBT). Which one makes the most sense? Knowledge Check Select the best answer. Integrate AI-based pre-selection. Knowledge Check Correct Incorrect The solution is: All answers describe useful approaches to reducing reading time when screening with DBT.

DBT reduces the recall rate in the U.S., because the recall rate there is relatively high using FFDM. In Europe, DBT slightly increases the recall rate, because the recall rate there using FFDM is relatively low. (For more details download PDF file Clinical_Performance_DBT.pdf under “Resources” in the upper right corner on this page.) Overall, prospective European screening trials show that DBT … … significantly increases the cancer detection rate compared to FFDM. … slightly increases the total recall rate compared to FFDM. … doesn’t change or slightly increase the PPV compared to FFDM. In addition, DBT screening results in a … … slightly higher patient radiation dose. This led to the development of the synthetic mammogram to replace FFDM as an adjunct to DBT. … change in ratio between detected invasive cancer/in situ cancers (more invasive cancers are detected). … longer reading time. This led to the development of new reading approaches. Following the market introduction in 2009, several clinical studies on Digital Breast Tomosynthesis have proven the value of this technique for breast imaging.
