Abstract
Magnifying narrow-band imaging (M-NBI) is a useful diagnostic tool for distinguishing between early gastric cancer and non-cancerous lesions. In a recent multicenter, randomized, controlled study, M-NBI including moving images was shown to be more accurate than white-light imaging for diagnosing depressed small gastric mucosal cancers. However, the efficacy of M-NBI with moving images for diagnosing gastric lesions is still uncertain. In this study, we compared the diagnostic accuracy of M-NBI with still images only with that of M-NBI with both still and moving images, and tried to identify the additional benefits of moving images in terms of diagnostic accuracy.
