GASTRIC RUGAE AREA GASTRICAE

Gastric rugae – longitudinal folds seen in mucosa of fundus and body. More prominent in GC.

Fine reticular network of barium coated groves between 1-5 mm islands of mucosa. More visible in old patients. Absent in atrophic gastritis, enlarged in gastritis. More obvious in distal 2/3rd.
