This resource provides an atlas of common abnormalities that affect the gastrointestinal tract and includes all imaging modalities used within GI radiology, as well as plain radiographs, fluoroscopy, ultrasound, CT, MR, angiography, and nuclear medicine. Focusing solely on adult conditions, it features 13 chapters covering a separate organ within the gastrointestinal system and a final exam chapter reviewing all chapter content. Each organ-focused chapter is subdivided into sections related to diseases or findings of that organ. Large, high-quality images are presented so that they can be reviewed as unknowns. A discussion of the cases is presented as if it were a consultation— with a description of the findings, differential diagnosis, and final diagnosis. A brief discussion of the disease is included. The end of each chapter lists differential diagnoses for the chapter's specific organ. Full-color composite anatomical illustrations show the immediately obvious appearance of common conditions that correlate with major radiologic findings.
