Abstract
AIM: Chronic active gastritis and mucosal atrophy develop from Helicobacter pylori (H. pylori)-infected gastric mucosa. Therefore, to diagnose H. pylori infection with an X-ray examination, it is important to recognize the gastritis and mucosal atrophy of X-ray findings. The present study measured the efficacy of our training based on X-ray image-reading of chronic active gastritis and mucosal atrophy.
SUBJECTS and METHODS: The subjects were 38 radiological technologists and doctors engaged in gastric cancer X-ray screening (31 were radiological technologists). To verify diagnostic accuracy, we used X-ray images with H. pylori IgG antibody serum titer. The diagnostic accuracy was compared before and after the training session.
RESULTS: Our results indicated that the sensitivity and the specificity of diagnosis pre-training were 76.3% and 82.9%. After the training, these values increased to 93.2% and 89.7%, respectively (P<0.05).
CONCLUSION: We confirmed the effectiveness of our X-ray image-reading training for diagnosing H. pylori infection.
