Background Information: This case-based exhibit will review challenging digital breast tomosynthesis (DBT) cases with a goal to educate radiologists on common misses and misinterpretations to ultimately improve future performance.

Educational Goals/Teaching Points: We present our experience with DBT through a series of classic and challenging cases. Specifically, we will review detection of 2D mammographically occult architectural distortion and malignancies, occult lesions in dense breasts, fat-containing lesions, localization of single-view abnormalities, occult multifocal, multicentric, or contralateral disease, postsurgical breasts, and breast tissue complexity.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques: DBT will be reviewed in this exhibit with supplementary 2D mammography, ultrasound, MRI, and procedural imaging as required to complete review of the cases.

Conclusion: DBT can enhance a radiologist’s performance by improving cancer detection rates and reducing recall rates; however, there are several imaging patterns which can result in failure to localize the abnormality or in misinterpretation. Familiarity with these cases helps reduce these errors and enhance quality and accuracy.
