sections covering hepatobiliary, pancreas and spleen, gastrointestinal (GI) tract, mesentery and vascular, and abdominal wall. Each case is formatted as a two-page unit. The left page features clinical images, succinctly captioned findings, and pertinent clinical history. The right page includes the key imaging gamut, differential diagnoses rank-ordered by the "Top 3," additional diagnostic considerations, and clinical pearls. Each section has multiple differential-based cases and some of them include important "Roentgen Classics" cases with imaging findings characteristic of a single diagnosis.
