Diagnostic imaging techniques such as ultrasound, computed tomography (CT), and magnetic resonance imaging have rapidly progressed. Cone-beam CT provides excellent space by rotating a cone X-ray beam at 360°. We present three clinical cases of gastric lesions by 3 dimensional aerography using cone-beam CT. Preoperative diagnosis of early gastric cancer (Case 1) was revealed. In advanced gastric cancer (Case 2), the lesion was clearly observed from the intraperitoneal space. In gastric submucosal tumor (Case 3), tumor shape, size, surface, and site were clearly imaged, enabling a definitive diagnosis. Further study is needed, however, to improve diagnostic quality.
