Gastritis: Classification, pathology, and radiology

Gastritis has a broad pathologic spectrum and anatomic distribution, as wel l as an evolving etiology. The Sydney pathologic classification of gastriti s, which appeared in 1990 and was revised in 1994, emphasized the importanc e of combining etiologic, topographic, and morphologic criteria for establi shing clinically useful diagnoses. Using this revised Sydney pathologic cla ssification as a guide, we report a simpler and more practical radiologic a pproach to gastritis. We emphasize those types of gastritis that may be det ected on radiologic examination and illustrate typical findings.
