PURPOSE: To determine whether there are useful radiographic criteria for
diagnosing Helicobacter pylori. MATERIALS AND METHODS: Radiographs from
double-contrast upper gastrointestinal examinations of 88 patients with H
pylori and 41 control subjects were blindly reviewed. The results were
analyzed by means of receiver operating characteristic (ROC) curves.
RESULTS: Thickened gastric folds were detected in 39 patients with H pylori
(44%) and nine control subjects (22%). The area under the ROC curve was
0.62 (standard deviation [SD] = 0.05, P < .01). Among the 48 subjects
with thickened gastric folds, polypoid gastritis with thickened, lobulated
folds was detected in 24 patients with H pylori (62%) and four control
subjects (44%). The area under the ROC curve was 0.59 (SD = 0.05, P <
.01). No substantial differences were observed in the frequencies of
gastric ulcers, erosive gastritis, gastric narrowing, duodenal ulcers,
duodenitis, and duodenal narrowing in patients with and without H pylori.
CONCLUSION: The presence of thickened gastric folds was the best
radiographic criterion for differentiating subjects with from those without
H pylori.
