Our new EXPERTddx series is designed to guide radiologists toward logical, on-target differential diagnoses based on key imaging findings and clinical information. The books present the most useful differential diagnoses, grouped according to specific anatomic location, generic imaging findings, modality-specific findings, or clinically based indication. All are ranked by prevalence as Common, Less Common, and Rare but Important. Each diagnosis is lavishly illustrated with at least eight beautiful images, all annotated by captions that highlight the pertinent imaging findings. Hundreds more images are included in the eBook feature that accompanies every book. In classic Amirsys fashion, each EXPERTddx includes bulleted text that distills the available information down to the essentials.
