Abstract

Gastritis has a broad pathologic spectrum and anatomic distribution, as well as an evolving etiology. The Sydney pathologic classification of gastritis, which appeared in 1990 and was revised in 1994, emphasized the importance of combining etiologic, topographic, and morphologic criteria for establishing clinically useful diagnoses. Using this revised Sydney pathologic classification as a guide, we report a simpler and more practical radiologic approach to gastritis. We emphasize those types of gastritis that may be detected on radiologic examination and illustrate typical findings.
